The current layout system struggles to balance simplicity and robustness, leading to the use of a binary tree data structure that limits expressiveness and introduces unintuitive user interactions. To address this, an n-ary tree data structure is proposed, which allows for a more straightforward representation of relationships between panes, enabling intuitive user interactions such as resizing nodes without affecting their neighbors. Additionally, constraints are introduced to ensure the structure remains flat, with branching only allowed in specific cases where two elements are stacked in different directions. This approach aims to provide a balance between simplicity and expressiveness, allowing for efficient and performant layout management.
