Seeing as my programming skills are quite basic, I didn't realise how hard this was to implement.
Does this look like this is doable? Should I raise this as a feature request?
Also thank to you (Valloric) and kovidgoyal for looking at this and also to the both of you for creating such awesome software for epub users like me. Between the two of you, I think you are providing everything I need for ebooks (except the eink reader I'm after, which I'll gladly except if you want to send me one
), and its freeware to boot!
