I just finished organizing my audio plugins in the plugin manager and am now working on doing something similar with the installed Video Plugins.
With Audio Plugins I'm able to right click and Rename the default plugin name but when I try to do the same with Video plugins it displays "rename" and "delete" in the right click context menu, but they're always greyed out. So I'm thinking there may be a pre-condition I need to perform prior so these items aren't greyed out?
