(Let me preface this post with a warning that tweaking unpublished settings can break your system and applications.)
While I am a fan of the Terminal, sometimes remembering (or Googling for) the proper “
defaults write ...” undocumented setting to tweak a feature on a new build or a friend’s machine gets a bit annoying (mostly due to my increasingly old age…Hey! You, kids! Get off my lawn!). If you ever wanted the opportunity to really muck things up across your system and installed applications, then head on over to the “Secret” BlackTree page (yes, the makers of the awesomeness that is QuickSilver) and grab a copy of their preference pane.
Truth be told, I actually needed to change out the text on the login window on my Mac (for work) and did not remember the
/Library/Preferences/com.apple.loginwindow.plist file or key for it and just happened to come across the Secrets update today. I was impressed at the extent of its database of settings for all sorts of apps and the fact that it figured out which apps I had installed (so it only showed relevant settings options).
An example of the non-deadly, application-usefulness of Secrets comes from its Twitterrific preferences pane:
which provides access to some of the tweaks you can make that are published by the author but not available in the actual application preferences.
If you know of any cool, hidden preferences or have feedback on Secrets that TAB readers should know, definitely drop a note in the comments.
