Maybe I don't understand that you are trying to do... but if any block don't have to be visible to anybody why not to drag the unwanted block to the inactive items area ?
Sure dragging blocks around works fine (although it seems to be slow and cumbersome). But if, for example, you're going to have a check box that says "Enable Shoutbox", then the function behind that check box should work, shouldn't it? And if you're going to have toggles for visibility options, they should work, right? They did in 6.0! So I'm basically just trying to give the great Boonex team some help in creating a cleaner app. ;)
You are absolutely right :-)
