I found one more thing:
currently, it is not possible to flag an edit when editing, except when it gets flagged automatically, which makes life very complicated.
I think the most useful way would be to provide a third checkbox to surveyors labeled "Sight edit" that allows them to sight their own edit. This would then flag the version with the minimum requirement for sighted. To avoid mistaked, this should only be possible when editing the whole page, not for section edits.
Technically this could again be done like the automatied flagging: first saving, then parsing the saved version.
Bye,
