It's not clear why this physical object is a better solution to the problem than, say, a window on your screen. Feels like more of a hobby project than something that provides $230 of value.
I know a lot of people who really like things like the Stream Deck. This seems similar to that kind of a concept. I'd probably take the Stream Deck over this though, its a good bit cheaper and each button has a little screen on it. Having some physical knobs is an interesting twist on it though.
There are dozens of us who went through the ordeal to use MIDI controllers for stuff because you just want to touch a button and not alt-tab 4 times. cf. https://f5n.org/blog/2026/hardware-mute-button/ (part 2 is not published yet where I replace the Korg software with my own app using a Rust midi driver)
But yes, mine was 55 EUR, is universally usable, and it was a fun project. There is a reason I didn't buy a stream deck and there's also a reason I did not buy a 3d printer, design a PCB and do it from scratch.
