Vim-clap is different than previous finders because it uses the new
floating_win (NeoVim) and
popup (Vim) interface. File lookup and switching have long been what keep me out of Vim as my daily driver (clunky UIs, slow results). Nothing beats Sublime Text in this category, in my opinion.
But this looks pretty awesome. I might have to give this a test drive and see if it wins me back.
