seems you haven’t found the
alt+rightclick = reset
shortcut yet. like this you can reset individual pins to their default values or when applied to a node reset all of a nodes pins. also mentioned here: the user interface in detail#changing values in the patch
have you got the dont-panic-the-noobs-guide-to-vvvv already? thats a cheatsheet with all such useful shortcuts.
of course it is frustrating that they didn’t yet manage to visually decorate pins that are not set to their default. jeeez devvvvs, what are you doing all day?!
and about pins keeping their data after being disconnected:
thats even more unintuitive once you understand that with all primitive datatypes (value, string, color, enum) the behavior is as you noticed, but with all others (mesh, texture, transform, …) it is as you expected.
we kind of learned to like it that way…for now at least…
