Hi
Just a hint:
If you name the respective folders with the VST2-plugins same as the VST3 plugins already have, you can show all the related plugins into one folder in Cubase 6.
e.g. There is a VST-folder named “Distortion”. If you create a folder named “Distortion” into the VST plugins folder of Cubase 6, and place your selected plugins within this folder, it shows it accordingly in the “insert-slot” of Cubase 6.
Actionally this does not really solve the “problem”, but make the work easier than to search all the way for the desired plugin.
Cheers
