I got a Streamdeck a short while ago and I honestly don'T want to be without it anymore and I am only scratching the surface of the possibilities with it.
Just alone being able to switch scenes and toggle sources in invaluable. Need to go afk quickly? No need to alt tab, search for the proper source to enable it to show afk things.
Same with toggles for the model or for effects for the stream, all on one display.
I even programmed myself already some buttons for infos. For example I have my stream health on my streamdeck, if it ever drops or even goes off and windows hides the OBS Toast of the disconnect, I still instantly see a colorchange and know that shit is on fire.
Also even integrated it into one of my streamer softwares, a local TTS System. If a bad TTS comes in, I just need to press one button and the TTS for that person is gone.
And I even have already also started to use it off stream and use it to quickly access softwaresand functions from things. It's soooo helpful.
