New KOA3 koreader user here

Hi all,

I just discovered the jailbroken kindle scene through this video and am loving koreader. It took a bit to understand some of its quirks (I didn't realize, for instance, that "lock orientation" was locking you to either portrait or landscape view--I thought it was literally locking you to your current orientation, and was wondering how I could lock out just the landscape orientations. Turns out it was doing exactly what I wanted all along) and get used to a couple of the bugs I encountered, but once I understood and customized it to my liking, I found it amazing.

Now I need some help getting a little further!
