[1.6.0] — 2026-09-07

Changed

• The viewer is more resilient and easier to read when there is nothing to
  draw. A workbook with no formulas now shows a clear, localised message
  ("no formulas were found") instead of a blank canvas, and turns off the graph
  chrome (toolbar, legend, disabled search and filters) so nothing looks broken
  but inactive. The same treatment applies when the graph engine fails to load:
  the detail panel is hidden and the stats line is filled, matching the
  no-formula case instead of leaving an empty column. Esc now clears a
  selection and closes the detail panel from anywhere, and hovering a node on a
  dense graph gives a visual cue to identify it before clicking.
