Excellent idea! This would be especially helpful for adding notes to note files that aren't being worked on specifically at the time, Such as my "general observations" or "great quotes" files.
"high-end" Bible software like Logos should definitely support Mellel. Being able to do in-depth Hebrew research should go hand-in-hand with support for presenting that research in a Word Processor that's made for Hebrew!
