Problem

Session Properties in Perspective are shared across all tabs in a session. This makes it difficult to manage independent state when multiple tabs are open, as changes in one tab affect all others.

Request

Introduce Page Properties (per-tab scope), e.g.:

page.props.myVariable

Expected Behavior

Scoped to a single browser tab

Shared across all views within that tab

Independent from other tabs in the same session

Automatically cleaned up when the tab closes

Benefit

Simplifies multi-tab workflows and avoids complex workarounds for isolating state.
