Feedback Polybrush: Idea for brush loadout changes

One of the main problem we see when using polybrush is changing loadout are too slow: the slowdown happens at select/unselect the current palette.

One idea to fix this: allow mobile interface like "hold then select/unselect" gesture.

When holding down mouse left/right button and panning across the Current Palette, the loadout should be selected/unselected.

(See iPhone Photos app for example.)

 

Same could probably be done for the Brush Loadout panel.

But to be honest I am ok with just clearing Brush Loadout on palette swap, currently the previously selected prefabs are remains in the loadout which defeats the purpose?

(Also since whether you can remove a prefab depends on the Current Palette, not Brush Loadout, it feels kinda moot to have selected prefabs remain when we swap palette.)
