Intuitive to use, exceptional tree structure, movable nodes and sub nodes. imports from over a dozen different formats, uses anchors to mark lines in notes for quick locating later. I use it in preference to office365 OneNote. Best thing its FREE and as new versions are offered, they are always backwards compatible to databases created with older versions of software.
