Oops, you are right. I fixed this. It should be way faster. I can
navigate in your example file without much trouble.

Please let me know how it goes.

The last commits have nothing to do with unfolding.

I'm not pretending that overlays are faster than text properties,

With the current implementation property drawers add no overhead : last
commits reduce drastically the number of overlays active in a buffer at
a given time.

Indeed. I fixed that, too. Thank you!
