[phossler]

I'm glad I was misunderstanding 'something'

I probably used the wrong terminology, and I really didn't want to mess about too much by trying different things

I got as far as the attachment below, which looks like some components of the KFX PI's could be disabled. I was worried about the effect that might have on the main PI's

The gist of my first comment was that using the [Get plugins to enhance calibre] path, the button captions were (to me) a little misleading, in that an installed PI selected had a button captioned "Install" and that the Uninstall was on a right-click

The last time I used the Preferences path to install a PI was long ago when I had to load a PI in a Zip (I think)
