Hi everyone!
I think it could be a nice feature for improoving speed of work. Here how should it work:
- each created instrument (or sample if no istruments are used) gets a random color identification. It is displayed as a coloured rectangle next to instrument name edit box. Clicking on it with left mouse button opens a color selection dialog, where user can set the requested color. Right-clicking instantly changes color to new randomly generated one.
- in pattern view, a default background color is used everywhere, where no note is played. But each instrument cell's background (maybe note cell's too) until a ^^ or == is used has a current instrument color instead of default defined in color sheme.
-an additional feature would allow user to set genarated color's desired saturation and brightness (hue is random). An additional frame in Colors tab in Setup window. There is some room left

No more reading this tiny instrument number, you just SEE which instrument plays here!
Here is how I see it working:
