Add the ability to save topics or subtopics as "events" or "reusable topics". As a coach I could use this to plan my practices if I had a list of drills that I could just call up at will without having to re-enter them every time.
It would help if you indicated which version you are using.
For all recent Windows desktop versions you can call up the Map Parts tab, click on the topic or group of topics you want to save for reuse and click on "Add Selected Topic(s)" in the Map Parts tab.
To add the topic(s) to the map, highlight the central topic, main topic or wherever you want then added in the map and then just click on the saved topic in Map Parts.
When you save the topic in Map Parts, by default it will be saved in the Map Parts folder in the order it is saved and it is not possible to sort saved topics. You can however select the favorites folder and save it there or even create sub-folders in which to save them.
I don't think this facility is available in Connect.
