Fluent styling — each call returns a new element.

Row/Column flex alignment and inter-child spacing. flex/center/spaceBetween/… only bite on row/column containers whose children leave leftover space (no fill child); elsewhere they are the identity.

Double-line borders — meaningful on panels, identity elsewhere.

Opts a non-interactive element into the tab order (interactive elements are focusable by default).

Extra blank cells inserted between a row/column's children.

A stable focus identity: focus follows this key across renders even when the tree changes shape (without a key, focus is positional and can jump when elements appear or disappear).

Ergonomic key handlers that hide the true/false stop-propagation ceremony.

onKey binds an action to one or more keys; it consumes the event only when a bound key matches, delegating anything else to a handler already on the element — so several .onKey(…) calls compose instead of overwriting each other. Use Element.onKeyEvent directly when a handler needs the raw event or conditional consumption.

A handler returning true consumes the event; false lets it continue to the next candidate.
