Max 6 is awesome! Such a pleasure to patch :-) thanks.
Two little comments on the patch cords though:
1. When clicking on an object, would love to have all the related patch cords highlight. It would save having to hover over all the patch cords to find the right one.
2. Would be amazing to be able to choose their thickness. When opening Max 5 patches, it can get particularly busy. (Unless it's there, but missing it)
These are super minor suggestions, but thought I'd throw it out there.
