Links that preserve and add context

Following a link should add context instead of replacing it, while preserving the reading trail in the URL.

  • People retain details near their focus and landmarks farther away; similar interfaces can work well for large information structures.

    “humans often represent their own “neighborhood” in great detail, yet only major landmarks further away”Abstrak
  • Web users often maintain multiple contexts at once rather than browsing strictly linearly.

    “parallel browsing is more prevalent than linear browsing online”Abstrak

Priority

Central to knowledge navigation: stacked panels combine focus and context, while URL behavior, focus, and narrow-screen handling can be measured.

Experiments

Findings

Conditionally supported

Stacked panels kept all three previously opened notes visible and encoded the complete navigation trail in the URL, whereas a single note per page preserved no visible context. Two conditions apply: focus must move to the new panel, or keyboard users remain in the old one; and narrow screens need an alternative such as a title trail, because at 375 px stacked panels leave no previous context visible.
