Yup, lots of stuff that could be done to make the ebook-viewer more of a fully-featured ereader app.
Hopefully you'll get around to some of those mprovements sometime soon.
At the moment, it rather stands out as the only calibre component which sorely lacks usability.
Still a perfectly decent ebook renderer, mind you. But quite barebones.
Ah, well. I would use my Kindle anyway.
But what with the rise of Windows tablets and all (something I don't have
), I can see the ebook-viewer becoming very popular if it gains some new features.
