The missing UI extensions for Vim 8.2 (and NeoVim 0.4)!!

There are many keymaps defined in my .vimrc. Getting tired from checking .vimrc time to time when I forget some, based on the latest +popup feature (vim 8.2), I created this vim-quickui plugin to introduce some basic UI components to enrich vim's interactive experience: Well designed and carefully colored Borland/Turbo C++ flavor ui system, combined with vim's productivity. Can be accessed by keyboard only while mouse is also supported. Navigate with the usual Vim keys like h/j/k/l, confirm with ENTER/SPACE and cancel with ESC/Ctrl+[. Tip for each entry can display in the cmdline when you are moving the cursor around. Multiple TUI widgets available. Fully customizable. Compatible with vim and neovim. Written in pure vimscript, no other languages required.
