Glad you like the app!
You may be interested to know that I'm going to be putting out a major update to the app within the next few weeks. Nokia were kind enough to offer me some time with a Microsoft UI design expert, and he gave me all kinds of useful hints. I think the result is a significantly more 'polished' app, in any case.
I'll also be taking the opportunity to migrate the app onto Windows Phone 8 (so far it is still a Windows Phone 7 app, which runs on WP8 in a kind of 'comaptibility' mode). That will mean it's possible to open books directly from web sites and email attachments (and also from the storage card, though I have some more programming to do, to get that working).
I'll post an update on MobileRead at
https://www.mobileread.com/forums/sho...d.php?t=103358 once I've got that new release up and running. And I'll always be glad to receive feedback (in forum, or by email to
jim@turnipsoft.co.uk, or via the app's feedback screen, as you prefer).
