Mail's 'Include related messages' preference shows sent messages together with received in the preview pane, however it fails to show them in the message list. It also doesn't send them to the trash when deleting a thread.
I replaced Inbox in my favorites bar in Mail with Conversations, which is a smart mailbox containing all messages that are in Inbox or in Sent. Now, not only do I see related messages on the right, if I open a thread on the left, they're all there, too. Plus, when I'm done with a thread and I choose to delete it, all the related messages also get deleted, instead of sticking around in my Sent mailbox.
It's not immediately obvious that more options exist due to the new scroll bar display.
Open Dictionary (it lives in /Applications in case you didn't know) and select Dictionary » Preferences. Scroll down the list of options and enable the two British options. Then click on them and drag them to the top so they take precedence.
You can leave the two existing American options enabled for the odd occasions that they might be useful. This tip pre-supposes, naturally, that British English is a better choice for you than the US dialect.
The other options previously available in Snow Leopard appear to remain largely unchanged. (The New Oxford American Dictionary has been upgraded from the 2nd edition to 3rd.)
[crarko adds: Nice to have the new options for our friends across the Pond.]
10.7 adds a Quick Look option to Mail for viewing webpage URLs in emails.
In Mail, just right-click (Control+click) a link in an email and select
'Quick Look URL' from the contextual menu.
[crarko adds: When I tried this the Data Detectors in Mail identified some URLs and gave me this option. Curiously, with others right-clicking on them just opened the link in Safari. I'm not sure how it made the distinction. Also, the time it took for the Quick Look preview to appear was pretty long. It's probably just as effective to open the link in a browser. Nevertheless, it is a feature to document, so here it is.]
A previous hint described how to extract images from Keynote by opening the file package. The latest iWork versions use compressed packages which add another step to that process.
A simpler alternative is using the inspector palette within the program.
To extract the original image from an iWork application:
Select the image you want.
Open the inspector palette and select the Metrics tab. (The one with the ruler.)
The first item 'File info' shows a file icon and name.
Drag that icon to Finder and you have your original image.
Credit goes to Peter Bries in the Apple Discussion Forums for reporting this.
[crarko adds: I tried it, and it worked in Pages.]
Snow Leopard had introduced a very cool function in mail where you could scroll through messages by swiping three fingers up or down. Unfortunately this function broke in Lion.
After a lot of trial and error testing, I found the same function has now been remapped to swiping three fingers left or right. Don't know why this changed, but am happy that I do not have to shift between the trackpad and keyboard to read my mails.
Also pressing 'Space' takes you to the next message.
[crarko adds: What I found is that pressing the Spacebar will scroll down by pages in the current message, and then when the end is reached progress on to the next message.]
Upon opening Logic Express 9 for the first time after upgrading to Lion, I received a notification that some of my audio units were unavailable (one of these unavailable audio units was AmpliTube 3, which I use for all of my guitar tones!). Fortunately, the fix was very simple: I opened Logic Express in 32-bit mode, and when I returned to 64-bit mode, the previously unavailable audio units were functional again.
Here are the steps I took:
Close Logic Express.
Navigate to the Applications folder and open the info window for Logic; select its icon, and Control+click Get Info, or press Command+I.
In the Info window, click the box for 'open in 32-bit mode.'
Open Logic Express, allow it to scan the audio units and finish loading, then close it.
Open the Info window again and uncheck 'open in 32-bit mode' to return to 64-bit mode
All 32-bit audio units should now be available in 64-bit mode.
[crarko adds: I haven't tested this one, but it sounds about right.]
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.]
