tick boxes are really an option to design lv2 plugins. i think that, as
extensions, we can activate generic tools (such as 2D controlers with
oscilators) and even complete GUIs. these which, by its turn, can be
unactivated or disabled visually to save CPU processing. That is something i
will keep my eyes on.

i fell like this "plugin of a plugin design" is a bit funny, but it looks
reasonable and usefull after i took a look in the LV2 API. at the moment i
think that a generic 2D high resolution controller for managing 2 chosen
parameters would be nice. And a 2D low resolution (kind of a grid) as well.
Oscilators for automatic time progression of these parameters seems nice
too. does some other idea for generic (maybe visual) controlers comes to
