I like the way now works the Structure Panel. The only "problem" I find is when you switch from the App structure to All elements. Always the All elements close all the files tree. You need to re-open the structure. Could be a nice feature that leave open the element and level that you have selected on the App structure or at least remember the previous selection.
When you are working on specific details you need to open and reopen the tree several times. I hove I get explained.
