(at the device)
Not reread?
Oh well
I use Calibre Companion (android), It can launch Moon+ (without adding to the bookshelf)
When done, I use CC to mark the
Date the book was read
The Next time I Connect, I do it as a Wireless device Connection with Sync
This updates the custom column in Calibre
THEN, once the status has been saved
(at the PC: Optional)
I can then search for #finished:true <-my name for the custom field
select any books with a tick in the ondevice (AKA ondevice:true) column and select:remove Matching from device
The advantage of this is a Batch operation if you have many books to delete
or you can just delete the book in CC
