Drag and drop behaviour for the Layout Customizer

Sorry for the confusion; we haven't renamed all the wiki pages to  
reflect the new Layout Customizer name. The user test results are  
located here:


The results, as I read them, suggest that some participants had  
difficulty determining exactly where their portlet would land. On the  
other hand, this test was performed with a prerelease version of the  
component that was a bit buggier in some respects.

Hope this helps,
