Research and Notes

I have found a great way to keep hierarchical notes and sync them between machines ( even with different operating systems ).
I have recently started using KeepNote, the note taking and organization application to record my notes.  I am using mercurial and BitBucket to keep my notes versioned and synced between multiple computers.
There is only one issue that I have had so far, and that is the indexing database.  If you want to use a source control to version and sync your notes, make sure you add the index database to the ignore file.
And as always a screenshot of KeepNote with some notes.
