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.
EDIT: Looks like the official Powerline docs share this little trick now: https://powerline.readthedocs.org/en/latest/tipstricks.html
"" airline settings
" remove separators
" remove unused modes
" set second section to filename
" empty third and fourth sections
" put filetype in fifth section
my full vim config is on github .
While it's deprecated, the author is actively working on this: https://github.com/Lokaltog/powerline, which works well and has even more functionality.
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.
Not much help if you actually want tabs, granted.
and then you can replace one of the airline sections with it.
Also: thanks for publishing this!
Looks great btw!
