Currently you can show opponent names, races and map info for the last 5 replays automatically. You simply run it and add it to OBS or Streamlabs by adding a new Browser Source with URL localhost:8080
It may be useful for tournaments and leagues in the future, but for now it's meant for personal use mostly.
This is a preview version (v0.1) and has some glitches like on the map names so consider it as such.
