With the release of Tiger, the new Mail.app's toolbar look is the subject of great controversy. I think the change that I dislike the most is the new toolbar -- mainly because it just looks plain weird. An easy way to disable the toolbar backgrounds is to move or rename the following files (I put them in a "Disabled Toolbar Images" subdirectory) within the application's resources:
- "Inner" files: TB_Segment_InnerLeft.tiff, TB_Segment_InnerLeftInactive.tiff, TB_Segment_InnerLeftPress.tiff, TB_Segment_InnerLeftRoll.tiff, TB_Segment_InnerRight.tiff, TB_Segment_InnerRightInactive.tiff, TB_Segment_InnerRightPress.tiff, TB_Segment_InnerRightRoll.tiff
- "Left" and "Right" files: TB_Segment_LeftCap.tiff, TB_Segment_LeftCapInactive.tiff, TB_Segment_LeftCapPress.tiff, TB_Segment_LeftCapRoll.tiff, TB_Segment_RightCap.tiff, TB_Segment_RightCapInactive.tiff, TB_Segment_RightCapPress.tiff, TB_Segment_RightCapRoll.tiff
- "Middle" files: TB_Single_Middle.tiff, TB_Single_MiddleInactive.tiff, TB_Single_MiddlePress.tiff, TB_Single_MiddleRoll.tiff
I haven't experienced any adverse effects from "removing" these files, but your mileage may vary. I've also created a free application called DeButtonizer that does the task for you.
[robg adds: I also received a submission from omnivector with a pointer to his free program called Cage Fighter, which does the same thing. Personally, I actually like the new buttons, but I know the look is quite controversial -- some love it, some hate it, and there are very few in the middle.]
