Awesome to hear! Right when I was finally thinking of making the swap to Linux I found Sublime and couldn't bare without it.
Any reason there are only thumbs of the preview images? Can't really see anything.
Also a tad unfortunate about the UI redesign. I personally felt Sublime handled it perfect. It gives you exactly what you need. Nothing more. Nothing less. I feel the vertical tabs take up a lot of space and you loose a lot of real estate. Will it be an option?
Not sure if you ever read it, but I posted a suggestion about implementing a virtual window manager IN Sublime. I have yet to see anything like it in any editor and I think it'd be brilliant. Have each virtual window be nearly it's own Sublime instance. Would save tabs and windows if they're split and such. Possibly things like which project is open as well so you could have a different project open in each virtual window. Have ctrl+ to swap between them. Working on a big project you could have the back-end in one, front-end in another, etc.
