Your wish for some form of folding has not gone ignored.
I have been experimenting with ideas for it, because as I said I'd like
to avoid a simple "fold/unfold" operation, as it clashes with "zoom/unzoom".
My idea sofar, is to allow you to set a global scale factor for all grids
that have been resized to what is currently the minimum size. It would
actually render those to a bitmap, and then scale them down, say, 4x.
So you'd get really small graphical representations of grids you have
shrunken down, which is still more informative than a fold icon, and
they would work like current tiny grids do: you can make them readable
by simply zooming into them.
Sound good, or?
