VST3 handling in hosts continues to amaze me.

Seems FLStudio doesn't support VST3 plugins without custom GUI. The GUI ends up fully empty [pic1]

That arrow down is not to show/hide the GUI, but to access some options. some trickery then allows to change parameters on the sidebar panel. [pic2]

[pic3] shows how it is supposed to look like, using VST2 format.

Have we reach the point where nobody cares about plugins without GUIs, so much they wont even implement support for it? wow
