Let's hope Mantano is just busy with the trade show in September as they mentioned before......
While we're at this, I would like to suggest moving the bookmark icon to a little bit farther from the right edge because on some devices (including mine), the touchscreen has problems dealing with touches close to the edges, and sometimes it takes me a few tried to bookmark, instead of turning a page.
Cheers.
Edit: Ooops, apparently there's another trade show from October 12-16...

Think they used to be supplying the underlying technology to others, and probably new to this "deal-with-enduser" thingy...
