As you may know, and as mentioned in this hint, the Library folder can be made visible again by running the following command in Terminal:
/usr/bin/chflags nohidden ~/Library
Apple keeps making the folder invisible again with every System update, so it gets tedious re-running the above script. You can automate this by adding a Login Item with an AppleScript "script application" containing the following code:
do shell script "/usr/bin/chflags nohidden ~/Library"
Read detailed instructions for this hint, and download a ready-made script application file on the Red Sweater Blog.
[kirkmc adds: There are any number of ways to unhide the ~/Library folder. Macworld has an article with 18 different methods, plus a few more in the comments to that article. This hint also tells you how you can create an alias in your .profile file to easily run this command. ]
