It would be great to change the characteristics of a component and have that change propagate down through all linked “instances” of that component. I have a LOT of screens full of duplicated components that need occasional refinement and improvement, and updating each “instance” can be very tedious, even when using containers and dynamic properties.

Indeed, this is a feature that we call “Inheritable Components” and I’ve also seen called “Templated Components”. This is a major feature that is on the schedule for 7.3, along with 2-D vector drawing.
