One of the things that stops me from using neovim - regardless of any changes I'd like - is the removal of gvim. I like my gvim candy; SVG icons in sign columns, better modifier support in maps, drag and drop when in command line, $things_ive_forgot_i_use.
Likewise, I also believe the idea of onivim is worth a licence fee, even it turns out I can't get behind it. It just feels like one of those projects I want to see succeed, even if it isn't for me.
