Request: Extension for vim-visual-multi

[jamespharvey20]

(Similar to #1932 but different plugin)

vim-visual-multi is similar to vim-multiple-cursors, that allows multiple selections, so you can prepend/append to or replace all of them, and so much more. The link has gifs that show exactly what I mean.

It doesn't have as many users as vim-multiple-cursors, but looks like for many it may wind up being a replacement for it and several other addons for quite a few people.

When that plugin is "active", meaning there are multiple selections, it basically adds 2 new modes, cursor and extend mode.

I think it would be great if vim-airline had an extension so the mode could show CURSOR (or C for a short name) or EXTEND (or E for a short name) instead of NORMAL/N. Cursor mode is similar to normal mode, and extend mode is similar to visual mode. [1]

g:Vm.is_active shows if one of vim-visual-multi's "new" modes are active, and g:Vm.extend_mode differentiates between cursor and extend modes.

I opened an issue in vim-visual-multi, originally asking how to differentiate between its modes, but then I edited it once I found it. If any input is need from the author, that might be a good place to ask for it.

Not sure how hard it would be to set custom colors for these modes in vim-airline, whether done through the themes, or left up to the user to custom define.
