Save and restore vim window layouts

WIP

Automatically save window layout and let user revisit it.

Based on brilliant dedowsdi’s answer on vim stackexchange.

Setup

Add mappings:

" no default mappings are provided, map it in your vimrc
nmap <F3> <Plug>(WinlayoutBackward)
nmap <F4> <Plug>(WinlayoutForward)

Change layout history size:

" default is 20
let g:winlayout_max = 40

Known Limitations

Still looking for solutions.

1. Fugitive buffers are not properly handled.

2. Doesn’t auto save layout on split window size change, for example, when you change it with mouse. (though sizes are saved if triggered by existing autocommands)
