Ghost controls or......

Many components have color input. Sometimes if that input was numeric, it would be easier to work with it.
Some cases the turn around is using a Control that has numeric values.
The problem is that those controls after appear also in the filter controls menu, that is not always what we want.
If we make a Group, and those controls are inside the Group, they don't appear in the menu anymore.
But the side problem of all this is that including components in a group seems to slow down FF (at least for me), especially if the group is big, repeated or if there are 5-6 groups.

Then I thought, what if we had some "ghost controls", useful for the filter making, but not appearing in the filter menu?

Clearly, an even better solution would be if we could choose between the color and the numeric input in some components, this way connecting a Control would not be necessary.
Easy examples are components like Add or Multiply, where sometimes having a color input is useful, but other times a numeric input would be better. Also Switch with numeric inputs would be very useful.
