Gr8 app, can be better

This is the most useful app for studying chm books and annotating. I was using the previous version from a long time, but that was useless. The changes have made this app as one my favorite. Still, I would like to have a pen (writing tool), highlighting as iBooks or kindle (just touch and drag to highlight) rather than touching and then selecting the lines.
I would also like to report a bug. After enlarging an image and then minimizing it, the highlighting tool is disabled! I have to close the app and then reopen it to work.
