I’ve uploaded a new version to extras-devel with some improvements. In scrolling mode the books are now loaded one section at a time unlike previously when the whole book was loaded (this caused some problems with large books). The toolbar has buttons for navigating between sections.
There’s now a slider at the bottom of the screen which shows current position as percentage. By moving the slider you can jump to different position.
I’ve also made improvements to how progress, bookmarks and annotations are saved. If you had the previous version installed I recommend removing the database (/home/user/MyDocs/books/bookdb.db)
GSoC is coming to an end and for the rest of the time I’ll be focused on bug fixing, refactoring and documenting.
