There is a new lock documents option in Time Machine Preferences. Click on the Options… button. Now you can change the auto lock time with different time periods presets between one year to one day.
The possibility to shorten the time to lock the document after editing makes it easier to use a document as a draft for another document without manually locking the document to avoid editing that previous document. For that purpose Auto Lock within hours would be nice.
[crarko adds: Is there a defaults command available for more fine-grained control of this? Post in the comments if you discover one.]
Preview in Lion adds the ability to annotate a PDF document with an image of your signature.
WIth Lion you can add an image of your signature to a PDF file. This allows you to send a signed PDF form without having to fax it. There are some tricks to getting a good signature image. Here's what to do:
Open Preview » Preferences » Signatures. Press + to add a new signature. A Signature Capture window will then open.
Use a Sharpie or other broad dark marker to sign your name very large on a blank 8.5" x 11" sheet of printer paper.
Be sure there is plenty of light on the page as you hold it in front of the camera. Do not let shadows fall within the viewing area. Don't use paper that has writing on the reverse side.
Hold one finger over the Enter button as you move the paper toward the camera. Align the signature along the blue line and hit Enter when you see the signature you want.
You can have multiple signatures. For example, create a signature with your middle name. In addition to your signature you can create handwritten symbols such as check marks, faces, or phrases.
Paste the signature into a document by selecting View » View Annotations Toolbar, then selecting the Signature tool, click on the signature you want to use, then click on the document where you want the signature to appear.
[crarko adds: This is a very welcome, if somewhat overdue, addition to Preview.]
The LogMeIn Hamachi MenuBar item is not quittable. There is an item 'Quit,' but however you try, or even if you stop the process in Activity Monitor, it won't quit. I tested this on 10.6 and 10.7, so problem on both. But enabling quitting is really easy.
The problem is that Hamachi is implemented as a launch agent in Mac OS X. So every time it quits itself or gets quit through Activity Monitor, OS X automatically relaunches it due to how launch agents work. They automatically restart when quit. So the solution is:
Go to /Library/LaunchAgents. Note: Not your user's library, but the system wide library.
Find the ...hamachi.plist. There will be some leading qualifiers (hence the ...) but there shouldn't be more than one Hamachi plist in there.
Save/copy it to a safe place, in case you want to re-enable it later.
Delete it from the Library.
Restart the Mac.
Please note that you probably should delete the hamachi-plist in daemons as well.
Also note, that after this hint, it is NOT needed that you run the menubar app before opening Hamachi. Hamachi works absoluetly fine wihtout the menu extra.
[crarko adds: Logmein provides an uninstaller, which removes the menu item as well as the application. As a recall a restart was required after that, although I can't absolutely swear to that.]
New IM and Profile fields have been added to Address Book, and others have been expanded. You can add them to cards by going to Card » Add Field and picking the new field you want.
For example, Skype has omnipresent for years, but Apple's Address Book had no field to store a contact's Skype name. Now, the IM fields can be specified as: Facebook, Google Talk, Skype, Yahoo among several others.
There is also a new Profile section in Address Book, with Twitter, Facebook, LinkedIn, Flickr, MySpace and Custom labels, although there seems to be something lacking.
When I filled in Facebook with a contact's name and saved the changes, clicking on the 'Facebook' label, there were two options: 'Show Profile' and 'Show Photos.' They didn't work. But, adding profile.php?id=nnnnnnnnn where nnnnnnn is the profile number of a contact, will indeed get you to their profile.
[crarko adds: Welcome additions to Address Book. Hopefully it will continue to improve in future updates.]
Mac OS X has long had the Go menu in the Finder. Within it there has long been quick Finder access to folders. The shortcuts listed there have also been usable in Open/Save dialogs (with the exception that going to the Desktop in an Open/Save dialog is done with Command+D, not Command+Shift+D like is used in the Finder).
10.6 added the Documents folder to the Go menu. Oddly, though, its Command+Shift+O shortcut that could used in the Finder was not available in Open/Save dialogs. 10.7, though, corrects this and users can now use it to get to their Documents folder in any Open/Save dialog.
[crarko adds: I tested this, and it works as described.]
After upgrading to Lion, Many of my databases would no longer show dates that were in the default format. Instead they showed Asian characters for the year. This is despite an early post on Apple's compatibility site that FMP 11 did not have that problem. Only Pre 11. But it still does. The solution can be tedious for large FMP systems with lots of windows with many date fields but for now this is the only solution. A FileMaker update which corrects this is promised for August.
You must go to each date field, or select several at once, and change them to a CUSTOM date format. You can make the custom format the exact same as the default, and it will still correct the problem. If you select several date fields at once to change their format, make sure the only thing you change is the format. (A good hint in itself.)
[crarko adds: Yes, it's obscure, but there are a lot of FileMaker users out there. Let is know if this works.]
if you are choosing to use the window restore feature also known as Lion's Resume feature, here's how to override this feature at the time of quitting the app.
Hold the option key while pressing Command+Q, or selecting the Quit from the application's namesake menu, and all the open windows will be discarded. In the application menu the Quit menu item will change to Quit and Discard Windows.
I was reading the hint about the Library in the Go menu, when I got curious to see what other menus change when holding down the Option key, and this is what I found.
When installing Lion's version of Xcode (4.1) you may get an error that iTunes must be closed before installing (even if it appears to already be closed).
This is pretty frustrating since I had no other applications open during the install. But in Activity Monitor, iTunes Helper (the Start up Item I always forget about) was still running. Force quitting that will let the installer finish. Just an FYI for those trying to install.
[crarko adds: I'm guessing this conflict is caused by the ability of both iTunes and Xcode to communicate with iOS devices (soon wirelessly).]
The new version of Mail in Lion has a nice Conversation View, which shows messages in thread form (like Gmail). I like this view, but the main problem that I had with it was that, to see messages that you've sent in that conversation, you have to move to Sent Mail.
Luckily, Mail lets us show messages we've sent as well. Here's how to enable that:
Go to Mail » Preferences » Viewing. Under View Conversations, check the Include related messages box. Conversation view is now complete.
[crarko adds: I tested this, and it works as described.]
Mail 5 in Lion includes a view option to show contact photos in the message list. This is great for people, but what about RSS? Instead of a generic person icon, you can get something better.
Create an Address Book contact with each feed author listed in the email block (they don't have to be actual addresses). To find the RSS author or group name, save a copy of a feed item and look for the "X-Mail-Rss-Source-Name" in the .eml file.
Depending on the contact you setup, you may need to organize your feeds or smart mailboxes by conversation to see the result.
