No it isn't. I get portevents for every parameter change sent
from the UI, even when there is no automation at all.

Done that a year ago. 


As for managing windows, Ardour itself behaves in way I find 
really annoying. When you close a plugin window it is not just
hidden, it's destroyed. So when the plugin UI is opened again
it has to be reconstructed from scratch. Ardour is just decent
enough to remember its previous position, but that's all.

What should plugins do if they want a file selection dialog ?
Keep it open all the time ?

Ciao,
