Palanor's desktop chrome has two tiers of navigation. The primary rail is the narrow vertical strip on the left with icons — Home, Intel, Relate, Resources, Help, Feedback, Settings, plus your avatar and your org logo at the bottom. The secondary rail is the wider panel that shows the modules and tools inside the active pillar.
The secondary rail is collapsible. By default it stays out of the way so your workspace gets the full screen.
Three states
The rail has three states.
Collapsed. Only the primary icons show. This is the default — best for Scenario Builder, Lattice Canvas, the Relationships pillar, and any other view where you want maximum real estate.
Peeking. Move your cursor over the primary rail and the secondary rail slides out as an overlay. It does not push your content — it floats above it. Move your cursor away and it slides back.
Pinned. Click the round toggle button at the right edge of the primary rail. The arrow icon becomes a leftward arrow, and the secondary rail stays open as part of the layout (it now pushes your content right, like the old behavior). Click again to unpin.
Where the toggle lives
The toggle is a small circular button at the right edge of the primary rail, vertically centered. It shows |→ when collapsed and ←| when pinned open. Hovering it before clicking previews the rail.
What persists
Your pinned-or-not preference saves to your browser's local storage. Across sessions, the rail remembers whether you prefer it pinned or collapsed.
Why the change
The Scenario Builder, Lattice Canvas, and the upcoming CRM surfaces benefit materially from the extra horizontal space. The old behavior pinned the secondary rail open at all times, which was right for module browsing but wrong for the long-form authoring surfaces where every pixel of canvas matters. The collapsible pattern keeps the navigation legible while letting the work breathe.
