I did a search and it didn't show any posts mentioning StreamDeck. I'm surprised actually since this is becoming a commonly used device for streamers. I use polypop with OBS since OBS can do multiple streams at one time. I've kinda sorta got my streamdeck xl setup to operate OBS remotely to stream our table top game, but I built all the scenes and transitions in polypop because I like it better. It would be nice to see some streamdeck integration, and at the same time it would be nice to operate polypop on my streaming machine but have the streamdeck plugged into my gaming laptop (has the books and D&D Beyond among other things) at the table, and those buttons setup to control polypop over the network. Specifically, and I'm still something of a polypop noob, I'd like to control my hotkeys at a minimum along with the audio options (sound out and microphone buttons in the polypop interface).
I'm guessing polypop with have more functionality and additional features in the future. If those features are interactive, it would be nice to see streamdeck support for those as well.
I love the app. Keep up the good work!
