I've always found various solutions that use git for sharing configuration files cumbersome. I set out to make my own simple version control system, and a lightweight web application where I can browse and edit them remotely. The main idea is that paths are aliased to simple names, so I can say `dotfile pull i3` and it will install https://dotfilehub.com/knoebber/i3 to ~/.config/i3/config
Overall the project is stable and I use it daily for all sorts of miscellaneous files.
