What do you think about adding a category above Lounge for...
Undocumented New Features
To post announcements and discussion of new features we find in Mac OS and other common software (like Firefox or Ghostery etc)
It may not see a huge amount of new threads, but would be a great resource for users to browse to "see what handy stuff they've missed" on their macs.
(in addition to unexpected switches, actions, and settings, this could include "useful information hidden out of view" and handy easy terminal commands like AppleShowAllFiles)
