This is something I've talked about before also, but I'll try again with a feature request. Ever since the first time I opened Vuo, the big play icon of the Refresh port on the nodes has been inviting me to click it, but absolutely nothing happens when you do that. I think clicking it should send an event to that node and it should execute whatever it would do when an event is sent there.
I know that currently you can use the output Trigger ports to send events manually when editing things, but that is an extra step that slows down live coding, you need to create another node to connect to it anyway.
So my request is simply this:
Send an event to a node when you click the refresh port. (or ⌘-click). I would prefer just left-clicking.
Also, when you right-click a refresh port, it should give you the option to "Fire Event"
I think this would help a lot for Vuo beginners to understand the event triggering. When you can manually do it, it makes sense to connect something to it to automatically fire it.
