I just want few small things fixed in current version, e.g, asynchronous refresh of project directories (or at least better version of remate hack http://ciaranwal.sh/remate/ ).
Finally, I'd pay additional for a Linux version.
I bought TextMate about 2 years ago and couldn't be happier with it. I've extracted way more value than the ~$50 I spent on it and would be happy to plunk down another $50 for TM2 if there were compelling reasons.
It seems unreasonable to buy software solely because of what you expect out of it tomorrow. You should buy it for what you need today.
EDIT: I'll add that I don't think that this is a greedy proposition. While I know a lot of people are truly thrilled with TextMate, I wasn't. I didn't ask for a refund, because I understand what it's like to be an indy developer, and thought I'd gamble that Alan would ship the features I'd need to switch to TextMate over Emacs when the 2.0 release got out the door. That gamble didn't pay out, which I'm okay with; 2.0 never shipped, and I'm not mad that 1.0 failed to materialize with the features I needed. But I also don't think it's fair to say I shouldn't get the 2.0 release, when I almost certainly would have asked for a refund based purely on the 1.0 release. I doubt I'm the only one in this boat--especially given how many blog posts I've seen over the last several years as developers, frustrated with TextMate's lack of progress, have reverted to Vim/Emacs/BBEdit/what-have-you to get the pet features they want.
