something that might be interesting for the plugin API:

At the moment, there might be unwanted changes to the document between 
sending its
state and receiving the answer back leading to 'wrong' applications of 
e.g. highlighting
and jump positions.

For this, the MovingInterface provides some "lockRevision".... concept, 
that one
can lock a document revision, send the data of that and later translate 
the cursor/ranges
based on the old state.

This could be used for the symbol outline, too, to still jump to at 
least "more right" position
even after editings.

For my highlight callback I tagged the lamba with some QPointer to the 
view, perhaps
even some more generic "tag each request with a QPointer to a view if 
wanted" might make sense,
too, then some "is this still the right view" checks are easier (and 
safer for the "view got deleted" case).

Greetings
Christoph
