I, unfortunately, had most of my plugins setup as the installers wanted, and tried to do some "house cleaning" later on. I believe I actually made it worse. When I loaded C3 for the first time, the scan time took awhile. I also have Waves, but rarely use them, so I deleted the link in plugin options and do not have to deal with the many plugs in that program. Also, I find my usage of the favorites folder being dominant. I have MANY plugins still, but really don't find it being a problem, especially with the "insert plugin" search box. I also am finding myself using the same 12-20 plugins on most everything, now that I know what works well, and what doesn't.
