My workspace is normally one very big xterm with vim, split into six or more buffers. It would be really helpful if it were more obvious which one was the active buffer. Right now I'm using the presence of line numbers for this:
augroup BgHighlight autocmd! autocmd WinEnter * set number autocmd WinLeave * set nonumber augroup END
but this means that when I change buffers my code jumps left or right, which is annoying. Plus, I'd like to be able to see which is line 94 even in an inactive buffer. So is there any way of changing the colours of the line numbers in the active buffer?
