I use Axon Idea Processor
all the time.
Mindmapping is just part of what it does, and if you only want to use it for that you might not find the presentation aspect as polished as you would like.
My main use for it is creating notes for speaking - collecting points and subpoints, moving them around on screen until happy with the layout, using a hierarchy of colour Red, Blue, Green, Brown, Black to indicate levels, and usually printing out one A4 sheet landscape from which to speak for 20-25 minutes.
On a regular basis I open a particular Access table, excel spreadsheet and Word template. One click on an icon I created in Axon opens them all.
Weighted decision trees, critical path analysis and some simulation models are other things you can play with.
You can export to html. I'm hoping for better export to MS Office programs in the future ... Because it does so many things it may take a bit of time trying it out to get a feel for its potential, but I reckon it is worth investigating (no association other than a happy user for the last 10 years or so)
