Easily the best reading app! Useful, but simple and clean. Sometimes too clean, though. I would suggest adding more useful little features, like, for example, being able to change the order of notes. Edit: Ok, so I found it. Apparently, I had to tap the text again for my keyboard to come up. Thank you! Yeah, editing the notes from the menu would be great! Also, it would be perfect if their order in the menu could be changed. Right now, they are always sorted from old to new.

Notes can be edited. Tap the actual highlight on the page then tap the notes area and it'll show a dialog where you can edit the notes. Do you mean you want to be able to edit the notes from the list in the drawer without visiting the highlight?

Please, please, please, DON'T add pdf support. Or cloud of any kind. Or OPDS. Keep it doing one thing, one thing only, just do it right. Like explicitly support e-ink devices which don't tell the program what they are. Even the library management and book selection is, frankly, better off in a separate app.

My experience has been mostly positive, however selecting text is somewhat broken. It seems to work as expected on most of a page, but as soon as you try to select more than a single word within the top two rows of text it wildly flips pages and selects numerous pages of text. This is quite frustrating.
