A project or family can be cluttered with ref planes. Removing them can be risky - you can't see for what they are used. They could host elements, be used to align elements (like the top of a wall under a stairs), to constrain elements etc.
As a rule of thumb, we name essential ref planes. At least, we should. But that's not always the case. And then there's the orphaned ref planes, created in skewed or angled views that have been deleted, so you'll never find those ref planes again.
My idea is to add more info to ref planes, like if they are used for any of the above (and preferably more).
And it would be very handy to create a schedule for ref planes, so they will all be visible - even the orphaned ones.
