Hi,
It will be great if we display optionally existing modules under this. Then it'll be to the users to see them or hide them.
For Example: i have a simple module that displays the weather of the user's zip code. I want to make it optional. So by placing that module under this, i can leave it to the user. If users like weather module then they'll not hide it and if they don't then they'll hide it.

Please share your thoughts on it and its possibility.

I think you are using a Text/Html module so can we have a work around for this to embed existing module under this one ?

Yes, that sounds like a good idea and I'll consider it for a future release. It may be easier for me to add that functionality into the Aggregator though since it already has the ability to include other modules. Your other option is to use the min/max button on the container to allow the users to hide the module. That won't totally get rid of the module but at least that way they could show it again if they change their mind.

This is actually a great idea for the core - kinda like the drag-and-drop UIs- but at least users could customize the page a bit with a few clicks... anyway - until it makes it into the core container framework this would be a good feature...
