This is the most general feature request I’ve ever done I think haha!
There are in the Key Commands a few commands you can invoke by first hitting a QWERTY key and then a number.
Recall Cycle Marker X, To Cycle Marker X, To Marker and also Workspace X.
This is pure genius!!! 
Can we just have more of those is my request?
Like
Zoom Preset X
Macro X - and you can sorta sort your macros by naming them with a number as the first character. This will probably only make sense for a handful of commands.
Logical Edit preset X - like the Macro X
Gain +X dB
Gain -X dB
on top of my head and I surely miss some obvious ones.
I like that! +1.5
Please!!
