If an annotation is tied to a highlight, there is the possibility that a
user will try to create an overlapping annotation. Currently, the
annotation code prohibits it: if you try to create a new highlight that
overlaps an old one, you are instead dropped into the annotation editor for
the old annotation. Overlapping annotations aren't that easy to create now
that it is word-selection that is used for generating highlights, though it
can still be done (in a hyphenated-word-sequence, if you tap on a hyphen you
get the whole sequence while if you tap on a letter you just get the word).
But once code gets produced for highlighting a larger block of on-screen
text (anybody wants to write that code for the annotation branch???) it will
become easier. I suggest the following behavior, but would like any better
suggestions.
1. If a new highlight overlaps one old highlight, just merge the two
highlights and throw the user into the annotation editor for the resulting
highlight, with any annotation that the old highlight might have had being
there. (Currently users are thrown into the annotation editor whenever they
make a highlight, since highlights are just anchors for annotations.
Eventually, we can make this be configurable, perhaps.)
2. If a new highlight overlaps more than one old highlight, check if the
4000-byte limit on annotations would allow the annotations on the old
highlights to be merged. If so, ask the user whether the highlights and
annotations should be merged into one. If not, tell the user to delete some
of the annotations manually first.
