Hello, I'm just trying out TextMate and I very much like the feature for collapsing brackets. (I remember seeing a post on some mac blog about using OmniOutliner to write code just so a similar feature could be achieved. Anyway...)
However, I have a suggestion. I have trouble distinguishing between the little triangle icons used on the left side. I was thinking adding color to them would make it much easier to see which is the top and bottom and which is collapsed. So I looked in the resources of the app and found the graphics files and tried changing them. The colors I chose are perhaps a bit much, but perhaps this post will inspire someone else (or the developers) to come up with a better color scheme.
I went with a red-yellow-green stop-light color metaphor. Green is the top of an open triangle. Red is the bottom of an open triangle. And Yellow is a collapsed triangle. If that makes any sense...
Basically, I changed these files: Folding Bottom Cap.png -> tint Red Folding Collapsed.png -> tint Yellow Folding Ellipsis.png -> tint Yellow Folding Top Cap.png -> tint Green
I've attached a zip containing my newly tinted PNGs. I'm not sure if this mailing list will let attachments go through, but if it does, enjoy. Otherwise, I guess you'll have to tint 'em yourself.
