I've been a long time user of EditPlus and Netbeans as my text editor & IDE respectively. I recently discovered Sublime Text which I absolutely love!
But my #1 issue by far is as the OP specifies here - I find the tabs in Sublime Text 2 to be currently unusable as soon as you have a number of files open - I'm kind of surprised it hasn't been flagged sooner - or has it already? I generally have a lot of files open and am used to using Tabs for my file selection, and EditPlus and Netbeans (and Eclipse as mentioned above) and most text editors have a way to handle this. EditPlus allows multiple rows of tabs, and Netbeans has a similar model to Eclipse above, except it also has left/right arrows.
Netbeans Tabs (When you click the down arrow, it lists all open tabs):
I also noticed there's a 'change request' logged at: sublimetext.userecho.com/topic/1 ... down-menu/ (Kind of surprised it doesn't have more votes)
