Well welcome again. I'm sure you will find it better on this side once you get used to a few things that are different. If there is anything that is preventing you from using TM as your main app, I would love to know what that specifically is, and I'm sure Allan is interested too.
There really is just one reason; my windows don't remember their positions. I'm on the "spatial team", and I have no tabbs in any program, and after a few hours of work I have like 10+ finder windows open. I need a window in the same space I left it. BBedit provides this, TextMate does not. I usually never bother with project things and such (which probably proves that I either work inefective or that I never worked at anything that big), instead I launch the files I want from the finder, and when I do launch that file, I want it at the same size, place and settings that I left it. THAT is the only reason for me not to switch right away (oh, and having to pay some money hehe) If the program had some "save workspace on exit" thing that could work as well, but I'd really want some database somewhere with lots of windows settings.
