This is fantastic! I've been working for a bit on a project for converting mind maps into slides. One feature I really liked was changing the level of depth of items. Let me try to explain what I mean. Say you're brainstorming and create a tree/toc of your slides. Then you start filling in the items for each slide. While you're doing so, you realize that slideA requires more details, so you turn the slide into a section and it's items into slides. Similarly, another section with multiple slides becomes less important, so you turn that section into a slide slideB and its slides into items of slideB. The reason I like mind maps/trees is that these operations can be easily done by changing the level of depth of the items, e.g. via drag & drop. I really like this idea of a simple markup for creating slides (plus the fact that it's text, so easy to version), and if this feature of making easy to change the level of depth of items could be integrated I think this would be a super plus!
