Hello!
I was wondering if it's possible to customise the Calibre Viewer's interface itself? I don't mean the pages inside, I mean the brown strip that says "Open a book", the Table of Contents on the side, etc.? I'm familiar with a bit of CSS, which I expect is what this is styled in?
Anyway, thank you in advance! I have nothing but respect for Calibre, and I'm very proud that a fellow Mumbaikar developed what is pretty much an industry standard now.
