One of our users is interested in having a Communities widget that gives more flexibility and options. Currently there are only two options in Edit mode: change the title of the widget and allow for sub-communities to display. See this thread for more details and our back and forth on the issue. I'm wondering if there is a widget like this already in existance or if there are plans to have this widget show more options in future releases?
It sounds like your community would like to have a more complete navigation of spaces and subspaces available in that widget. We are doing work for the 3.5 release, coming later this year, that should address the needs I saw in the thread you referenced. Thanks for letting us know about your needs, I'm glad we already have something in the works to help out with them.
