I know what you mean. I had originally hidden all VST2 plugins from the plugin list in Wavelab so it’s less of a mess to look at but I’ve had to unhide a few VST2 versions to use until the VST3 version is stable.
FabFilter, Waves, Brainworx/Plugin Allaince, and NUGEN all seem to be okay regarding VST3. UAD and Sonnox are of course VST2 only right now so that solves that.
