I see what you mean. But after some thinking, then how to draw multiple cables from outputs (like you can do as it is), without disconnecting/ moving the cable/s that's allready is drawn from the output, without it's going to be at least as annoying as things work now?
You would have to
1. use double click that perhaps can be hard to do because you need to be precise,
2. use left - right click or (Can MAC do this without usinh the apple key or something like that?)
3. use a computer keyboard key plus a click on outputs to add a cable from there. (I Prefere not to use two hands, as that can be very annoying in many situations.)
4. You have to be able to activate seperate cables in a output. (But how to do that as it is. One needs to be very precise if even possible.)
All 4 ways can be more annoying than the excisting.
It could be done. But i don't know if that's a good idea.
Have you thought about this? Do you have an idea to solve this?
