It sounds like it’s two things really:
-The generic remote editor itself, which Imho needs a major GUI overhaul and should be integrated with key commands, macros and the PLE
-the remote control protocol - and as suggested, opening up SKI or something similar so that developers can take hold of it.
It seems every time SB dabbles in hardware controllers they get discontinued, or they are woefully underpowered, unless it’s Nuage of course, which is at a whole different level (and price point).
I can only imagine business wise it’s a tough nut to crack, finding the right balance between development/features and price point/market.
But if SB aren’t going to do it, at least open up your SDK so other people can!!!
