The delay in leaving insert mode used to drive me nuts in vim-powerline. I posted an issue and the author pointed me to this helpful Vim config snippet as a workaround (original link gone as the vim-powerline issue tracker has been removed, so reposting as a gist): https://gist.github.com/brendonrapp/5944296
I imagine the delay that the README for this project is referring to might be the same thing, so hopefully it can be alleviated with this same trick.
I happen to really like this. I used a few lines in vimrc to make mine a little more practical for me:
"" airline settings
" remove separators
" remove unused modes
" set second section to filename
" empty third and fourth sections
" put filetype in fifth section
curious to see how other people have theirs configured.
I've spent hours trying to get powerline to work with the patched fonts on OSX and Macvim without any results. This is lightweight, simple and just worked out of the box. Also the light theme is amazing. THANK YOU!
Is there a nice status line plugin that isn't full of color / visual noise? This would be by far the loudest and most animated part of my vim screen. I've tried powerline too and found it little but a distraction.
I basically don't need to know which mode I'm in, either - if I somehow forget, or come back to vim after a while, I can just hit escape to reset its state.
