Is your feature request related to a problem? Please describe.
When editing a complex page, to have overview of its blocks structure, it is not enough to show the block’s anchors. It is hard to have a quick idea of where the blocks are.
Describe the solution you’d like
There could be an option to toggle “Show blocks’ structure”.
Describe alternatives you’ve considered
Alternatively, temporarily changing all blocks’ background color at once also could serve this function
An additional “Edit Structure” mode would allow to move blocks by clicking and dragging anywhere on a block, not only on their anchors.
