Research direction
Investigate the current layout system in fyne, particularly the CanvasObject type and how it handles positioning. Study the Cassowary algorithm for constraint based layout (e.g., the kiwi library in C++ or a Go port). Propose a design for integrating a constraint solver and discuss with maintainers on issue #4.
