I know this has been discussed, and a number of people have expressed their view that the TextMate icon isn't too visually pleasing already.
However, using TM in anger today, I keep finding myself searching frantically for the icon in the dock. It's so indistinguishable at a small size that I literally find it hard to see.
So I guess my point is that it's easy to dismiss concerns over the icon as a matter of taste. Unfortunately in this case, and certainly for me, it's a matter of usability - the icon isn't doing its job.
See attached!
I think I'm going to hunt out an alternative to use in the meantime, but I hope that's useful feedback.
