Rumor has it, that Lion makes the User’s library folder hidden. Which could make it annoying to power users that need access to the library folder.
One option, is to use the Go To Folder command, and type “~/Library”. That will open the library folder in a standard finder window.
Another option, is to “unhide” the Library. To do so, open terminal, and type:
chflags nohidden ~/Library
In addition, if you simply hold down the Option key “Library” appears in the “Go” menu of Finder.
