Freeze Orientation and Zoom, Add Page back Button.
I use charts in PDF format, and have to switch pages constantly, and have noticed a few things that I wish could be changed. First, if I am zoomed in on page 1, please stay zoomed in on page two. Second, I use my Android phone and doggone it, the orientation is touchy! Please allow us to lock orientation, so if I bump my phone, it isn't suddenly flipped, and zoomed out again. Also, if I do change orientation, lock in the zoom! This has been the most aggrivating thing for me. Finally, I sometimes have jump from say page 4 to page 10, can you add a simple go back or "last page visited"? It would make it so much easier. Especially once zoom lock is implemented. That auto zooming out is killing the joy of using your product.
Also, please PLEASE add "Connect when on WIFI only" to the settings! This app is a data eater! It hogs it like I have an endless supply, and sadly, I don't.
