I use Software Carousel and keep a permanent work area for VR (Vertical Reader). Whenever I have a moment to spare, I flip to the book I'm currently reading. A book might stay open for days, sometimes weeks, and then the HP would crash or lock up because of something else I'd done. My place in the book would be lost, as VR only records your position when you quit. Similarly, bookmarks are only saved on exit.
If you open a new book VR saves your place in the current. The open book dialog, invoked with / (forward slash), starts with the cursor on the current book. Open your current book and VR will save your place/bookmarks and re-open the same book at the same place. It's almost instantaneous.
Tip: Press [/][Enter] when you stop reading and you won't lose your place in the book if a re-boot is needed.
