I agree. I work on a lot of large frameworks having to scroll up and down the sidebar to see open files makes it pretty worthless.

The horizontal tabs are pretty worthless after 7 or 8 files are open.

Make locking it in an option

Another editor even let's you select how much it should take up in the side bar as a percent % -- even better!

It's one of the only things holding me back from using SubLime.
