Without exaggeration ThinkBuzan is becoming what Barcelona is in soccer. With iMindmap 6.0 the company is on top of the mind map software market. The version history (made with the new tool Flowchart available in 6.0) shows that ThinkBuzan has a major upgrade almost every year. The branch target is brilliant. Moving and making branches (normal or box) is easy, smooth and fast. Add-ons like grouping and snippets make life of a mind mapper easy. In case of a branch you are using very often (e.g. in projects), make a snippet, save it and use it whenever you need it in a future mind map.
iMindmap does have weak spots as well. The cleaning tool for example (not new in 6.0) I never understood. I think that most readers will agree that the mind map shown has a nice well-organised lay-out. Applying the cleaning tool the mind map looks as if it has been hit by a Tsunami. Undoing the cleaning option, does not restore the old version (all the images are scattered over the canvas). Resolution issues when exporting the imindmap file have been improved in version 6.01 (first update of version 6).
The flowchart tool is very nice, but grouping and aligning is not possible (I used the app Ruler to align the cells).
Having said this, iMindmap 6.0 scores 93 % on 10 performance indicators (iMindmap 5 scored in the same test 82 %).
