Sublime/VSC Style Minimap

Hi, I was wondering if it was possible to have a Sublime style minimap in the gui?

For example, the akiyosi fork of goneovim has this on the right hand side :

There is a plugin for neovim that accomplishes something similar (minimap.vim), but its limited to the text rendering of neovim so it uses braille font (which doesn't look as good).

This may not be possible right now (I assume it would require multigrid support as you need to draw the window over neovim), but is this something you can look into for the future?

Sincerely Shaurya
