1- The ability to download and save images as book covers from the web browser. (It looks bad having most PDFs and Epubs with blank covers, or random text.)
2- Ability to execute javascript in offline HTML files. (for basic app support (I would be incredibly interested in writing a few Kobo programs with this framework))
3- Account backup files (I've had to force-off my Kobo a few times due to large epubs crashing the system, and when I reboot, My user data is gone, save a few stats)
