This might not be possible but always worth asking.

I have a number of different devices all of which have books on that have been loaded via Calibre. A problem I hit from time to time is that I may make an edit to a book in the library (usually correcting spelling but sometimes a bit more drastic surgery). I then upload the book to one of the devices. The problem then is it's easy to loose track of which device is "up to date".

Devices are mainly Kobo but there are a couple of Android devices.

Is there any add-on or other approach to being able to highlight books which have a different edited date in the library from the date of the file on the device ? I suggest using the date as size or a checksum probably wouldn't work where the file in the library was an EPUB but the one on a Kobo was KEPUB.
