I'm curious how many Handmade devs out there actually use vim. I don't use this plugin myself because I find the command line just fine, but I do love a good vim plugin.
I've been using vim for years, recently I started also using 4coder with my own vim-like customizations.
Until I discovered this plugin in the last week or so, I had been just fine with the command line as well. I use i3 as my window manager, so tiling all the things makes it quick and easy to swap between my code and my command line. Even so, the value I've gotten from this plugin is enormous. Not having to leave my editor and getting temporary splits is fantastic. It's similar to wanting the ability to build code directly in vim with stuff like :make.
It's invaluable for my workflow.
