finish https://github.com/ircam-ismm/catart-mubu/issues/120 LATER part:

• [ ] fix camu.process.* in edit mode
• [ ] fix comment attrui on in/outlets visible in patch, should not be too salient
• [ ] find a highlight frame colour better compatible with all Max colour themes than our beloved orange
• [ ] find a comment colour better than cyan for the overview
• [ ] check keymixer colours
