Hi,
one feature I would really love to have would be the ability to have tabs without needing a project (if there is I really couldn't find it). I really like tabs but I only occasionally work using projects. Having the option to say "any files I open are opened as a tab in the current window" would positively rock.
Also, having a way of telling TM that you want all your windows full screen at 0,0 would be really nice and far more usable than what the default OSX behaviour provides.
