Another observation on the Plugin Browser. First, excellent tool in the arsenal - absolutely.
Okay, if you run an Effect from within the Plugin Browser, that Effect is NOT listed in the History dialog, rather the Plugin Browser "Effect" is listed. For instance, if I use the Plugin Browser and choose Shape3D, then I get a spherical object on the canvas. In the History dialog there is a record of the Plugin Browser being used, but not which Effect. I'm sure it's not as simple as that, but it might be confusing if multiple Effects are used via the Plugin Browser?
