Removed the custom faces from the module in favor of setting them in doom-themes itself https://github.com/hlissner/emacs-doom-themes/pull/467
First round of fixes suggested by @gagbo, including moving some keybinds to be alphabetical, fixing some paths, and pinning the package version.
Created a new Minimap module based on minimap.el from ELPA the module sets some DOOM-specific config, and better defaults. Also added keybindings for it.
