I’d love it if the ‘Customize Component…’ option were in the contextual menu you get when clicking on the network background of a component (right alongside Open Parent Parameters, perhaps).
Always a bit of a slowdown to pull back out of the component just to get to that option.
Involves 2 menus, but you can RMB to Open Parent Parameters, and then RMB on the Info ‘i’ icon on the floating parameter dialog to open Customize Component.
Also whilst we’re discussing custom parameters it’d be great if the edit custom parameters window were made available for the script SOP and script CHOP too.
