Vim-Byline is a simple statusline implementation. It has separate colors for the file extension and file path. It changes colors on inactive windows. And it shows the read-only and unsaved symbols in red.
There is no configuration at this time. Please send me a message if you would like any particular configuration settings.
You can override the colors. The following colors are used.
hi StatusLineFile guibg=#9bfb9b guifg=#000000
