Glad you are working on this! I've been pretty disappointed at how non-standardized highlights (and comments) are for ebooks. Taking notes, highlighting, and 'active reading' are generally worse on electronic platforms and the potential to be have easier access to my generated content initially seemed to compensate for that... until I realized that I couldn't sync it up at all and none of the formats seemed to be compatible. That said, I have avoided Amazon entirely and am not particularly interested in the spaced repetition aspect so I won't be signing up just yet. Would love to hear if/when you support Calibre, Kobo, and/or Moon Reader.
