Happy to see the Telltale Tool going cross-platform (and waiting for a possible Linux port

, I tried downloading Monkey Island 104 for Mac and unpacked it, then started it ("MonkeyIsland104" or so). After a first play, I went ahead and renamed the ".app" to "Tales of Monkey Island 104", because the other name looked strange, and re-started the game. I noticed just now that the settings (and savegames?) are saved in $HOME/Library/Telltale Games/{basename-of-.app}. This means that when someone plays some levels, saves their progress and then decides to rename the .app folder, their savegames would be "lost" (or at least it would not be obvious for the user to know how to move the files to the correct folder).
Maybe you can determine the subfolder of $HOME/Library/Telltale Games/ by using the CFBundleIdentifier or some other (hardcoded) value that does not change when the .app is renamed, which would prevent this problem.
OTOH, maybe it's just me who renames the apps, and so it's a non-issue (having the apps have a "cute" folder name by default might prevent users from renaming their apps..).
