Firstly thank you for great program.

Suggestions:

Ability to move Categories up and down in file tree i.e. just change order.

(drag and drop does not allow you to change order only placement in tree)

Spellchecker. If possible.

Queries:

Is it possible to upload my lessons so that other users may download them and use them?

Any possibility of adding jmemorise to www.studystack.com?
