FreeMind

+here is the idea:

+freemind labels for nodes

-build a label list for the document/application, user-added labels

-searchable labels

-select by label, format by label

-display branched structure by label

-icons = labels ? custom icons + open-src icon library addon

-export format/structure based on label

+these modifications would greatly improve freemind as a powerful information aggregation/management/interpretation tool!
