Hi,
I would like to suggest a minor cosmetic change:
The fx plugin list is kind of overlay window, which is nice. But the synth plugin list remains within those tiny borders on the left.
I would like to suggest to make the synth plugin list behaving the same like the fx plugin list, making it a overlay window.
Also please make those overlay windows 100px more wide. Since if you’ve added your personal tree structure to the list and also maybe renamed some plugins (I sometimes add the vendor name to the entry e.g. since I will forget what is hidden under a plain naming “compressor”), the names are shortened very soon, which makes navigation a bit annoying.
