update properties of a drag'n'dropped chunk?

Hi all,

I really like the concept to create html-chunks with properties which can be pasted into the content via drag & drop.
Finally, after drop it, the form with the properties pops up. That’s great.

But what if the client would update these properties later? I think it’s not the best solution to let him change in-code...
How do you solve problems like that in your pages?

Thanks for answering,
