I'm a perfectionist, and I usually end up delaying my work on a new website i'm building because I know it will take me hours to do because of minor but very important inconveniences.
Just making these containers responsive (on 3 breakpoints) took me about 3 hours~. Whenever I move an object, it will try to position itself in the dock either to the left or right, this is very annoying.
Most us us want fixed elements, not fluid or positioned in the dock, if we need to position it, we can manually enable that. Please disable automatic positioning, and percentages for margins.
The other issue is that when I go to edit another breakpoint, all my elements are all over the place, or within each other, it's a complete mess, fixing the design, positioning, and sizing takes most of my time.
