"I've shared a couple of maps and it's hard to tell if anyone did anything. It would be nice to get notified via email if another user besides myself does something in the map. Of course, need the ability to turn notifications on or off for people who don't like to get too many emails."
"We shouldn't only be able to see in the file list, if a partner changed the map, but also if we've already opened it since his last done changes.
Not an every change done by one of us, is an important one. So it should be possible to annotate the file with regard to the relevance of changes. You could offer us such an annotation method, in the moment we save the file. The annotation should be visible in the file list. We should be able to understand at a glance, if we could, should or must take a look inside.
The already suggested emails as announcement, should also be customizable. Two options would be important:
a) Email - yes/no
b) Email only if important changes - yes/no" [from mentalwaves]
