I'll use that for sure then.

What I've also noticed is the 'sliding' effect of the new page tree.
The tree is nice, better, cooler, more responsible _BUT_ slower.

Hopefully the opening effect is customizable too,
because the sliding effect is not as good as just
displaying sub pages instantly when expanding them.

Just my 2 cents,
Thomas
