Request: back out of nested list without exiting mdt

[sebastian-rand]

Many thanks for this useful tool.

I have a feature request: I use some nested lists, that is, lists with headings, so that when I select the list in mdt, I asked to choose from the headings, and shown the list under the chosen heading only. I would like to be able to back out of the list back up to the headings again, without exiting mdt and starting over again. As far as I can tell, that's not possible at the moment.
