I´m using cloud version since begin of year. I like it so much! nice initiative!
On this new version I found a behavior (I think different from previous) that reduce usability aspect.
here is the case:
Once you create a new sub topic (by pressing Tab) and start to type (from keyboard) xMind edits parent topic, not new Sub topic created. It demand user to click on new topic to edit.
It happens also when you are creating a topic on same level (pressing Enter). on this case xMind edits previous "highlighted" topic.
