To me its a completely useless function. I, and only I, decide on my site layout. I build it the way I want it for a reason. There are ample ways to move things around in Admin.

Sorry guys, just my opinion.

I just think it gives a nice bit of interactivity to a site. Make it that much more convenient for a member to use, so that they can have the blocks that they need / want, instead of everything that I, as the admin, need / want there.

Especially if you have a "hompeage" with TP.
