I would like to use my own color scheme for my patches - one colour per voice. I can achive this by clicking often to get some cables and take only the color I need at this time and erase the others. Picking up from your color palette would make this easier. But
making a screenshot seems to use allways the stackcable logic – color by lenght. It would be nice, if the same colors I see in the patch were used for the screenshot.

And finaly it would be great to have a text function similar to the knob marker, where you can write a text at any place. You can use this for example for documenting the channels of a mixer or a sequencer.
