I added rich presence for discord. 

It isn't exhaustive and haven't decided how granular it will be. There are many states I'd like to share but also if I make unique art for each instrument - maybe even difficulty, and even variations for each -  it can get to be too much. 

The image resolution required by Discord is very large, but the actual display of it is really tiny, so it can't be very detailed or informative. It kinda just gets lost

There are also roll-over descriptions that provide more info (not shown here). I have several situations I haven't completed and some of the art is will change. I have placeholder art for Stars achieved when the song ends and there is opportunity for more options, like if new score is achieved, etc. For the play state, I could show when multipliers are reached or broken, but here it also makes sense to have custom art for each instrument, as the track is not the same., so that makes for a lot of variations. or the image should be more generic to apply to all.  

There is also an option to show a little tiny image on top of the "large" image, but I noticed at least on mac the small image masks out a large portion of the bigger image even tho that's not how it is shown in the documentation. I had planned to use it to show which instrument is active but for now i'm leaving it out.
