The option to use proportional fonts is a very rare feature in vim-like text editors (the only other way I know of is to use terminal vim in mlterm), so for people who want this the screenshot is good advertisement.
In fact, after reading you comment, I promptly startet to install it (still compiling as I type this). My use-case is creative writing: I'm very used to vim keybindings from coding, but prefer to have a variable-width fonts for writing.

The font in the screenshot is `Iosevka Slab` which _is_ monospace -- `fvim` currently syncs with the neovim grid system and doesn't support proportional fonts well.
Sorry about the confusion -- I think you've already discovered that (after 46 minutes)!

Aha, looked like a proportional font was used to me. I'd use a more well designed monospace font for the first impression!
Visited its page to have a look... I'm not sure why they'd put a screenshot with a variable width font, which automatically puts lots of people off when it comes to coding...
It's like having a screenshot of your bitmap editor, and showing it editing goatse.cx...
