Hi there,
FIRST and FOREMOST:
THANK YOU SO MUCH FOR CALIBRE!!!

This is such a great tool. I use it for many years. No idea what I would do without it.
The only real thing I miss is a good way to get the highlights out of my mobile reader (it is MoonReader+, I use the paid version) and into Calibre.
This is something that I miss a LOT since I use this feature very much.
I wonder about the proper place for this question as I don't know whether this would be a feature of Calibre or rather something impplemented via plugin.
All I can say: MoonReader allows for syncing books via Dropbox, Google Drive and WebDav. I use the last option. This allows me to not only sync my reading position but also all highlights and similar data.
Is there any way to implement a solution that grabs this type of data and puts it into Calibre?
Thank you SO MUCH once again!!!
