Feature Request: Layout Modelling

This is a request to implement various positioning algorithms used by GUI frameworks such as grid layout, flow (vertical/horizontal) layout, masonry.

Also other options could be to position components using various patterns (e.g. mirror, rectangle, circular or on a bezier path)

Could be useful when doing ui protyping!

The issue does not name any files, tests, or entry points. First define the scope among grid, flow, masonry, and pattern-based positioning, then map the selected algorithms to the editor's existing component model; done means an agreed implementation scope and working layout behavior.
