Why can we no longer close the subforums in IPB 3?

What's the point of having them in a normal forum if they're open all the time?


This is what I mean, this is the skin help forum ...

http://forums.invisionpower.com/forum/309-skinning-and-design/

In 2.3.x we can close them, just like the categories on the front page.

minor skin addition that can be done quite easily
