Post subject: Categories Collapse to Top

This is a simple mod that works in conjunction with phpBB 2.0.23's default forum category collapse behavior.

A couple of the design goals in my own project are:

1) maximize real estate
2) anchor the screen to minimize 'jumpiness' in page transitions

To this end placing important info near the page top when ever possible is always kept in mind.

When the forum categories are 'collapsed' this mod moves the open category to the top of the list of categories. That's it.

The mod may or may not work with other category collapse/rollout mods.

If it has already been done, we can delete this post. If there's a better way to code it, I'm all ears.

Code:
