I adnotate once in a while some passages
ANYTHING works since the resolution is small and the method is based on IR (like in trip alarms). For instance the finger in a glove
There is no settings on the adnotations, these are simply bitmaps stored in the meta directory of the individual book. SInce these are bitmaps, changing the font size, thus forcing a repagination, would change the location of the bitmap and it would adnotate other parts of the epub (
eg page 3 contains now a different text than at the adnotating time).
