This is a simple tracker for Distrandomiser. It provides both ability and map tracking. It's pretty simple - you just hit the buttons, and it marks that as obtained/completed. Web based, so it'll work on pretty much anything. Just open it in your browser and add a window capture source in OBS.
I'm sure somebody will make a more complex tracker eventually, possibly as a fork of this one. This is just meant to be a basic tracker for the purpose of tracking, and I guess kind of a demo for what a tracker could look like.
