'Send to device' is pretty convenient, and I can also see "In Library" column from the Device view. I wonder if is there a quick way to sync book in device back to the corresponding book in calibre? After read, new annots are saved in pdf on device, I want to sync this new books back to calibre.
Now I find add to library(from the Device view) will create a new book. Even if "In Library" column value is true.
I found this
Sync back to Calibre. Do we have a buit-in function now?
