I use split windows, both horizontally and vertically, in Vim all the time. I’ve always wanted to be able to split the window and then start a command line shell within that window but up until now that has just been a dream.
Conque lets me do exactly what I’ve wanted, create shells within Vim. In insert mode you interact with the shell as expected. In normal mode you can scroll back through your history, yank text into buffers, paste and manipulate text. Best thing ever.
