If you browse mind-pad.com for a while then you can surely learn what is “frames” and “object-orinted” mind mapping. But we have to explain is to our prospect as there is probably no good analogy in a paper and pen world. But if it were… read Hobart's Mindjet Weblog. The general idea is that if we have a metaphor for something (computer mind mapiing is just like a paper and pen mind mapping) it wodn’t be easier to sell these new things.
We do our best to positionate “frames” metaphor. For now we call it “Custom Frames” meaning topics (frames) that can be designed to have custom fields… If one have more ideas about positioning frame approach? It would be great to have a comments about this.
