It's been on my todo for a long time (and some prep work, like moving 
highlighter related functions from synedit to highlighter  have started....)

It will be limited though => because folding needs to know the full deal 
(as scrollbars depend on the total of visible (unfolded) lines.
Of course, if no nodes are folded => folding doesn't care (even if 
switches on). It's only when a node actually is folded => then folding 
needs to verify it still exists.

Another improvement (but much less noticable) would be to separate 
structural and visual scan.

certain info (like making a "+" red) is only needed when you scan for 
display.
It doesn't matter for the overall structure. Also many keywords make no 
difference for the structure (as far as the highlighter is concerned) 
"deprecated" for example. In structural scan it doesn't need to be a 
keyword.
