I’ve been using the matrix views quite a lot in recent years, and have upgraded my monitor to a display with a considerably higher ppi.
That makes using the matrix view harder.
The matrix views are drawn without pixel images, so my suggestion is to
Make the matrix views zoomable
I suggest a mouse modifier context and/or actions to zoom where the mouse cursor is.
Ever since I have to hand out per-track stems to Netflix, I’m rendering dozens of tracks on every session. This zoom could help make this easier quite a bit. My eyes would appreciate the help too.
