Frustrating. Bookmarks don't appear to work. It always opens at chapter three now, including all bookmarks. A lot of fiddling to get usable font settings. No setable delay for screen saver. Easy to accidentally advance to next page. Sometimes will not advance to last partial page in chapter. 23 Feb 22 The more I use this app, the more I hate it. Bookmarks worked for a while, now stuck again at the beginning of a chapter. Continuous reading mode does not work in portrait orientation.
