It's like tabs like you have in Chrome. I use when I have too many buffers/windows to handle it, and when I run 2 different projects next to each other. I know there are other alternatives, but for now it suits me.
There is ony thingy that drives these fanatical tinker crazy. I can't change the way how the tabs looks. I added a screenshot:
As you can see, you see
[X] # which # stands for number. I would like to remove the
[X] # by default in all Elscreen tabs. When I took a dive in the source code of Elscreen, I couldn't find where he defines the numbers, so that I could disable it in my Emacs init setup.
I ever thought Lisp was easy, but I can't really find any numbers and cross defined to disable it.
Any input would be appreciated.
