I've been careful to not step out of Vim's own file structure, but might have
overdone it with plugin settings. Function definitions in autoload, commands in
plugin/commands.vim, statusline in plugin/status.vim, keybindings in
after/plugin/binds.vim. Some colorschemes in color/, an INI plugin in
pack/, where the other plugins are. Using submodules, but there's a list of
plugins too.
Warning:
; and : are reversed. Arrow keys are used for aligning
windows, not moving.
