UI suggestion (z-index, negative margins)

[brandadesign]

Hi guys!
When I using z-index or negative margins can become a problem to select the desired section.
The ideal would be to have a list of sections in the left panel, selectable with mouse and with a double click enter in its settings.

Thank you so much and sorry for my english!

I merged this issue with #1165, which is on the same subject so we could deal with it more efficiently.
Please feel free to continue the conversation there.

Thanks for your feedback!
