Actually, in the original thread I made the same point.
Please see that discussion for this and other points.

That's good news (new to me). So it sounds like even the most hopeful
wanna-haves of the discussion could perhaps be realized without too much
trouble.

This sounds great. I really hope someone with the time and knowledge adds such
a feature soon (even though, to be clear, I personally do not have much need for
it). I think it would be very handy for many users - most welcome.
