vim-duochrome

more than just a distraction free colorscheme (though you can copy the colors/duochrome.vim file to your colors folder for just that)..

purpose

create a colorscheme that not only displays a minimalist distraction free palette but dynamically configures the vim environment (feature set works best with Gvim) to provide a distraction free workflow for concentrating on writing and coding

features

auto-centering of text area within window (window width and textwidth dependent)
auto-hyperfocusing on insert mode
auto-fontsize for code and markdown
minimalist dynamic statusline content (name + state + col/%/wordcount)
toggle cursorline (dfm, highlight, underline)
toggle breakchar (and line highlight)
toggle line wrap (disable textwidth)
toggle relative number
toggle column ruler (cursor, fixed)
toggle expanded statusline (path + tag/atom + utf-8 code)
toggle background (light, dark)
toggle fontsize (code, prose)

todo considerations

user defineable delay timings for gui refreshes
handling of unavailable optional plugin dependencies
update vim-colors-duochrome with the dark and diff colorschemes as separate colorscheme only plugin
