First, thanks to chaley for giving me details about Calibre Companion. I returned my Windows 8.1 tablet and bought a Samsung and I immediately bought Calibre Companion. I'm delighted beyond words!
1. It looks like my user-defined columns don't come along to CC when I download books from Calibre. True?
2. If I update my desktop Calibre to massage and merge tags, how does that new tag structure get to CC?
Thanks.
