That's a better way to do it than properties in my opinion.

Whether extension was required or not, my only point was that for
small lists the only reason I still use OO or Excel was for the
ability to dynamically narrow a list.

Given org narrows outlines, I thought it might fit.

I'll have to play with babel now!

This is why I use @address@hidden, the separators are your cues. There's an
LR symbol, but I don't use it often.

That alone is a good reason to make sure separator lines are preserved.

Thanks.
