[Major Feature Request] Layer View

Hi team brizy - 

As someone who builds a lot of "broken" layout/modern design sites that have zero padding or overlapping margins or absolute positioning, Layer View is absolutely vital and is so missing in Brizy.

For example - especially when building column-in-column layouts, when Blue column has zero padding, Red column goes right up against the Blue col arrow/handle and is practically impossible to get (sometimes it's possible, but it takes patience and time- both of which are in short supply) https://www.berrycast.com/conversations/f6cba7b2-34d4-5908-b647-eeef5407c9b8

This problem could be quickly solved by putting the Red column handle on the opposite side, on the left side - just like Row handle is opposite - so every other layer sort of flip-flops with it's handle positioning. That way there's enough differenciation to not have the handles disappear completely underneath each other.

Another example is for rotated elements with absolute positioning I sometimes don't know where they go if a setting takes them too far away - and Layer view would be helpful in finding them.

Also, when using z-index heavily, objects are impossible to access/edit without a ton of tweaking and re-doing.

Also, when pulling up blocks into the negative margin (for hyper stylized sites) the Block handle disappears (like for making sticky header with a transparent background to overlay on the Hero block)

Also, even just in regular layouts - there's a moment where in Full Width layout, if the padding is around 50-75 in the block, then the Column handle disappears/is inaccessble.
