Yes, among many other things. I also made buttons for programs, websites, switching genres of music, volume mixing of various apps, etc.
It's basically a box of programmable buttons and knobs, and you program them to do all sorts of things. There's a secondary market of plug-ins for domain-specific stuff like Photoshop or Discord, and built in functions for running programs, media control and hot keys.
The intended use-case is that you can make a simple physical button action that works outside of the context of what's on screen -- great for situations where you are task-saturated, like video streaming or dungeon mastering. When your head is maxed-out on what you are saying to your audience, you want a quick one-button way to play the dragon attack music.
But for every-day use, I like it because it feels like I'm punching buttons in Apollo Mission Control! Start Reentry Burn Now!
No, there probably isn't a serious business case for it, but it's cheaper than a Corvette!
