What if operators could 'upgrade' similar to the way devices in bitwig can be 'upgraded' in the context menu (like going from a 2-band eq to a 5-band). Rather than dragging in a related op, reconnecting nodes and trying to match similar parameters, it could try and match the parameters and routing.
A simple example might be to go from gridpoints to radialpoints but keeping the translation and scale (maybe even the number of points). Or perhaps moving from the different feedback ops while keeping similar displacement and blur.
I like how there is sometimes a list of similar operators underneath the parameters. Really handy to get to know what's out there 🙂
