Thank you DoctorOhh,
Followed your instructions. . . pushpins gone.
Unfortunately It's not the pushpins I don't like it's the SPACE they use.
Guess I'll have to wait for the author of the plugin to put a setting in to disable the pushpins.
If you don't want to see the marked pushpins follow the directions in
the manual and substitute the attached image. Once done you can have as many marked books as you like but you won't see them marked.
