It would be useful to be able to convert mind maps back and forth between bulleted lists (with indents) or full-on mind maps. Being able to edit in either mode would be exceptionally powerful. Being able to switch dynamically, or to import/export to/from bulleted lists would allow the user to engage with the data according to their preference. I like mind maps. My team members prefer the concise bulleted lists.
This would also facilitate integration into other products in a more elegant fashion. Imagine being able to grab a massive bulleted list from WORD and drop it into MIRO as a mind map. Mind blowing!
