When you are at it, please add this to the Layers view:

• When dragging the section, add a horizontal line so you can see where the dragged section will end up and where it will be placed (the current background color is not clear). Right now it is unclear what will happen when I let go of the dragging. Sometimes it happends, sometimes it doesn't.
• Add three icons to each section/addon in the Layers view. That indicates where it will be shown: Desktop | Tablet | Mobile. Then I am quickly able to see which one I need to adjust. Right now this is the only way to see a clear overview of the page.

I really need this in this version. It is the main reason I like SPPB 3.x better because keeps all the addons of different window views. Perhaps you can add a button in the top bar next to the different window icons: "Show All Addons". To fix this problem.

We are planning to add back-end editor for SPPB 4.x, as it was in SPPB 3.x

I have question about your 1st request, can you give me more details. Becuase even now it's possible to have that

Please create a line bar indicator, demo (blue) so you can choose where to put the Addon/Column/Section, either above or below. It is also a clear indicator if it will be placed or not.

OK, I see now. Thx.

Keep up the great work!

I shared your ideas with our dev team, thx again

Lovely
