Just a suggestion....Why I want this feature? I think container in one of the good feature of DNN. But currently, the container need to insert into a pane, and only can put in up/down sequence. It's impossible to put in left/right side.

It is impossible to this this without modify the skin now if I want to make four text/html module in such behavior in content pane.

If I found a container it's very beautiful and I want use them to show such layout. The only way is to separate content pane into four panes. This is very inconvenient for end-users because most end-user doesn't know how to modify a skin. But if I can insert text/HTML module into text/HTML module than I just need to create a table with four columns and insert text/HTML module into it's cell.

Of course if I can insert a module in left/right side this problem can have solution also and this should be easier to implement.

How about this idea?
