0005 — Views: several named dashboards; File and View menus

• Status: accepted (owner request, 2026-10-31)
• Amends: 0004 (ribbon menus and icon buttons, single dashboard tab)

Context

The owner asked for several instances of the dashboard, each a named view with its own repository selection, while the repositories panel stays the one list of every repository in the project; for side panels that keep their entries on one line; and for a ribbon with File (Export, Open, Settings, Diagnostics) and View (Panels, Open new view, Styling, Full screen, Refresh) menus, keeping only the side-panel and theme icon buttons.

Decisions

1. Views are dashboard tabs. Any number of tabs with component dashboard in the dock (dockLayout.ts); each is renamable (double-click, or Rename view in Search commands) and closable, except the last. Names are trimmed, non-empty and unique (case-insensitive); refused changes say why.
2. Naming. A new view is View n with the smallest n not used by another view's View n name, counting from 0 (nextViewName). The single dashboard of an older stored arrangement becomes View 0, keeping its tab id so its settings carry over.
3. Per-view settings. Filters, display toggles, axis, zoom, collapsed/expanded rows and the repository selection belong to the view (ViewState, stored per view id in repobs.workbench.v1); the selection and the repository sort order are shared. Settings of closed views are dropped. The view state from before views (repobs.view.v2) becomes the settings of views that have none yet.
4. Repositories. The repositories panel lists every registered repository (with a Sort dropdown). A view hides repositories rather than listing the ones it shows, so a newly registered repository appears in every view. The panel's ticks edit the current view — the view last selected, clicked or focused — and say which view that is; each view also has a Repositories dropdown.
5. Menus and icons. The ribbon has File and View menus only; commands without a menu (the current view's display options, rename, zoom, repository sorting, adding repositories) remain in Search commands and in their own controls. Icon buttons: repositories panel, details panel, theme. Maximize view and Reset layout sit under View → Panels; Reset layout keeps every view.
6. Export and Open. Export writes one JSON file (format: "repobs-export", version 1): the server's sanitized annotation export (no transcript content) and every view's id, name and settings plus the arrangement. Open merges the annotations through the existing import endpoint and replaces the views; view settings are normalized on the way in (unknown fields dropped, invalid values defaulted) and the arrangement is used only if it parses and holds those views, else the views open side by side as tabs. A plain annotation export is accepted too. Files over 20 MB are refused.
7. Refresh asks the server to rescan everything now (POST /rescan); live updates make it rarely necessary.
8. Side panel widths. Repositories at least 280 px (default 300), details at least 320 px; stored side bars narrower than that are widened on load. Repository entries no longer wrap (ellipsis).

Amendment (owner feedback, 2026-10-31)

• Drag to pan. Pressing the primary mouse button on a view (not on a control) and moving more than 4 px pans its scroll area horizontally and vertically, like a map (useDragPan.ts); the click that ends a pan is swallowed so it selects nothing, and shorter presses stay clicks. Touch and pen keep native scrolling. The lanes show a grab cursor, the label column an arrow.
• Sort as an icon. The repositories panel's Sort dropdown is a compact icon button (its value in the name and tooltip), so Add fits at the panel's minimum width.

Consequences

• Each view computes its own layout of the repositories it shows; the details panel resolves a selected branch row against the current view.
• The e2e suite drives the menus instead of the retired icon buttons and covers views, per-view repositories, renaming, closing and export/open.
