I find that I’m often moving elements around, grouping them and ungrouping them, etc.
One thing that seems fairly (unnecessarily) tedious is moving an element out of a group and then moving it back to the exact location on the page. Currently, this requires me to drag the group out of the parent group (but not place it on another group accidentally). Then, I have to calculate the x and y coordinates relative to the page (which often requires looking at the heights of several elements and calculating the space between them, etc.).
It’d be nice if I could just select an element and then click “remove from parent” and have it decoupled from the parent element and positioned in the same absolute position on the page.
