Comment 1 for bug 1760316

Let's try to outline what we already have and why this does not work.

[EffectRack1_EffectUnitN],focused_effect
0 indicates no effect is focused; >0 indicates the number of the focused effect. Focusing an effect only does something if a controller mapping changes how it behaves when an effect is focused.

[EffectRack1_EffectUnitN],show_focus
Whether to show focus buttons and draw a border around the focused effect in skins. This should not be manipulated by skins; it should only be changed by controller mappings.
