Scaler Guitar View (Add a Capo Mode) (and other instrument restrictor)

In Scaler, in the Guitar View Section, Can you add a CAPO mode?
(a visual capo, that grey’s out note’s behind the capo, showing or giving nice visuals to patterns that work well in front of capo)
So the CAPO function would imitate putting a capo on a guitar neck.

Similarly, a made up Restrictor for piano, where all notes have to be between certain keys. this restrictor would be useful for showing different instrument limitations, or where you would like a certain instrument to play between piano notes. [insert chart of limitations of basic orchestra instruments]
The restrictor mode, would restrict the Octave and Key’s in which the Piano mode could play between (note sure if this already exists, currently using an older mode of scaler 2)
