A lot of games (most) have a number of steps or phases that the coding will make you take in succession. Those follow the order in the game, but it would be great to have an area at the top of the UI that game creators could add that shows which step/phase you're at, as well as turn number.
This chart/timeline would highlight the step you're on, and maybe could extend to show substeps and/or short explanations of what happens in that step. It would free up the chat and let the players more easily where they're at in the game. Maybe a timer could even implemented so that after a game you can see where you took the most time and your average turn and/or phase time.
We have this layed out as a github here https://github.com/kellyelton/OCTGN/issues/105
I agree it would be pretty cool.
