The Streamdeck is just a fancy macro-pad/programmable keyboard, and those are around in several areas since decades. Especially video- and music-makers have a pretty sophisticated experience there. But

But for software-developers I don't really see the value. We alrady do have our tools for managing macros and shortcuts on regular keyboards. Macropads don't really have much value there. Usually the trend is to reduce key-estate and build elaborated layer-interfaces, not expand them and waste desk-estate.

Though, I could maybe see some value if there would be support for animations on the streamdeck, and more scriptability.

Let me introduce your to Taran, the king of macros : https://www.youtube.com/watch?v=vhPLhfP1b_s

I guess I should point out that he uses it (along with some other unique systems) for video editing in Premiere.

I use a stream deck for a few common macros I type often while programming. It works great.

this is the sort of wondering that has led me to have a veritable collection of niche usb peripherals (including a streamdeck haha)

i hacked this up one day just for that purpose: https://github.com/bketelsen/godeck I don't use it for streaming on Linux, but for all sorts of other things.
