[LV2] UIs for mono plugins

If I'm not mistaken LMMS should not develop controls for external 
("plugin") UIs. Why providing controls in LMMS when they are already in 
the plugin UI?

My question was based on UIs the plugin brings: How many such UIs should 
we show and how should we sync the controls between two such UIs.

Apologies if this wasn't written clear, or if I got you completely wrong
