That's all very cool. Is there a good Android e-reader app that supports it? The features I most desire from an e-reader app are, in order of priority:
- The ability to quickly reference a Japanese/English dictionary
- The ability to sync progress between devices
- Good e-ink support (high-contrast menus, the ability to disable animations)
- Support for vertical text (extremely common in Japanese literature)
KOReader supports the first three, but not the fourth. If an app supported all four I would almost definitely switch.
Also, is there anyone distributing books in that format?
