DSM, ok good explanation. I do have some vision issues myself.

And I think I have idea how to solve that and save large chunk of space.
Names of "types" in the mixer could be made to display in bold, same size as on left side. It is comma/column separated, so should be fairly easy to achieve.

Or even get a little more creative and display "instrument types" in different color (perhaps user defined color?)

Unless... this column is serving some other purpose...?
