unable to toggle filter view (back): %w

Error message

unable to toggle filter view (back): %w

What it means

TUI controller error chained inside ToggleFilterView(): after successfully hiding the filter view, the code clears the tree's filter regex and calls ToggleView() to move focus back to a visible pane; this wraps that ToggleView() failure (i.e. error 30's path re-entered from filter teardown).

Solutions

1. Retry the interaction once the UI is idle; transient focus races often self-correct.
2. Use a larger terminal window so all panes including the filter line fit.
3. Upgrade dive for view-lifecycle fixes.
4. Capture the full wrapped chain (controller -> toggle filter -> toggle view -> gocui) and report upstream.

When it happens

Trigger: Closing the filter view (filter hidden) and the subsequent re-focus to Layer/Tree failing because SetCurrentView errored — startup races or views missing after layout changes, same root causes as error 30 but triggered specifically on filter dismissal.

Common situations: Pressing Escape/enter to dismiss the filter during heavy rendering; dismissing the filter immediately at startup; degenerate terminal geometry.
