## The problem

I'm trying to decide locally whether the local data or the remote data is newer and then sync either local data or remote data based on the date.

But currently the remote data doesn't have a date when the user last changed something there so its not possible to decide which data to take from.

## The idea

Add a date field to the library entry which shows when the user last touched the entry.

## Today

Just always take the highest chapter number and sync it
