Supports previewing and indexing of freemind files (.mm extension).
It uses the same approach as share-extras media previewers for share extension and Java XSLT for XML to text transformation which enables indexing.
For previewing you need to get the flash previewer from freemind or freeplane (fork). Should work for 4.0.x versions and on-wards.
