It's definitely high on my list. I've been giving it a lot of thought and planning but haven't started the actual programming on this yet because I haven't finalized how I want to do it.
I definitely get reminded of this quite frequently, though, because
@jon wants to track all his daylily seedlings. I am personally growing a lot of crepe myrtle crosses that I want to keep track of, too.
As was said above, this may end up being a winter project for me to program.
