+# Main Nav Gating Follow-ups
+
+Context: the desktop MainNav rewrite moved several workspace, account, tools, and marketplace entry points out of the old header/account-setting layout. These notes track product-contract questions that should be resolved before treating the rewrite as behavior-complete.
+
+## 1. Account-setting modal naming and moved destinations
+
+Current branch behavior:
+
+- `setShowAccountSettingModal(PROVIDER)` routes to `/tools?section=provider`.
+- `setShowAccountSettingModal(DATA_SOURCE)` routes to `/tools?section=data-source`.
+- `setShowAccountSettingModal(API_BASED_EXTENSION)` routes to `/tools?section=api-based-extension`.
+
+Old behavior: these calls opened the account-setting modal and switched to the matching tab.
+
+Question:
+
+- Since Provider, Data Source, and API-based Extension are no longer inside Account Settings in the new design, should this API still be named `setShowAccountSettingModal` for those destinations?
+
+Follow-up decision needed:
+
+- Either keep the compatibility shim but document that these payloads are now route destinations, or introduce a clearer navigation API for integration destinations and update call sites intentionally.
+- Re-check call sites launched from workflows, datasets, and app configuration. Some contexts may expect an in-place modal instead of leaving the current page.
+
+## 2. Integrations sidebar disabled entries
+
+Current branch behavior:
+
+- Integrations includes disabled entries for Trigger, Agent Strategy, and Extension.
+- These are visible but not actionable.
+
+Status:
+
+- Currently being handled separately.
+
+Follow-up decision needed:
+
+- Decide whether disabled future entries should remain visible, be hidden until supported, or be gated by feature flags/edition/role.
+- If they stay visible, define the tooltip or disabled-state copy so users understand why the option is unavailable.
+
+## 3. Plugin and marketplace status parity
+
+Old header behavior:
+
+- `PluginsNav` showed plugin install progress and error state through the installing icon and red indicator.
+- Installing tasks showed the downloading icon.
+- Failed or erroring install tasks showed the red status indicator.
+
+Current MainNav behavior:
+
+- MainNav has a Marketplace link, but it does not surface plugin installing/error state.
+
+Follow-up decision needed:
+
+- Decide whether MainNav Marketplace should preserve the old plugin task status indicator.
+- If yes, reuse the existing `usePluginTaskStatus` behavior instead of creating a parallel status source.
+
+## 4. Mobile/default account language entry
+
+Current branch behavior:
+
+- Desktop MainNav account menu includes Language and Timezone submenus.
+- Mobile still uses the default header/account dropdown path.
+- The default account dropdown does not expose the Language settings entry.
+
+Decision:
+
+- Preserve the old language-access contract across breakpoints.
+- The desktop MainNav path is acceptable; the missing case is mainly mobile/default account dropdown, including dataset-operator users on mobile.
+
+Follow-up decision needed:
+
+- Add an equivalent language entry to the default/mobile account path, or otherwise ensure mobile users can still reach language settings.
+- Keep this as gate-contract parity, not a visual requirement to recreate the old Account Settings sidebar.
+
+## 5. Apps and Datasets quick-switch/create parity
+
+Old header behavior:
+
+- `AppNav` could show the current app, list more apps, load more results, and launch create-app flows from the header nav.
+- `DatasetNav` could show the current dataset, list more datasets, load more results, and launch dataset creation from the header nav.
+
+Current MainNav behavior:
+
+- Apps and Datasets are static navigation links.
+- App/dataset quick switching and create actions are not present in the desktop MainNav.
+
+Follow-up decision needed:
+
+- Decide whether the new design intentionally removes these quick-switch/create affordances.
+- If not, add equivalent behavior in the MainNav flow without copying the old header UI directly.
+
+## 6. Branding-gated Help and Support behavior
+
+Old account dropdown behavior:
+
+- When `systemFeatures.branding.enabled` is `true`, the whole Dify help/community group is hidden.
+- That hidden group includes Docs, Support, Compliance, Roadmap, GitHub, and About.
+
+Current MainNav behavior:
+
+- HelpMenu keeps the trigger visible, but its content is gated by `!systemFeatures.branding.enabled`.
+- This can produce an empty Help popup when branding is enabled.
+
+Open question:
+
+- The old coarse gate also hides Support, but Support can contain instance-specific channels such as configured Zendesk or support email in addition to Dify forum/Discord links.
+- Confirm whether branded deployments should hide Support entirely, or keep configured customer support channels while hiding Dify official/community links.
+
+Follow-up decision needed:
+
+- If strict old parity is required, hide the HelpMenu trigger when branding is enabled.
+- If branded deployments should retain support access, split Support into customer-support and Dify-community items with separate gates.
+
+## 7. Paid plan Billing access from workspace plan
+
+Old header behavior:
+
+- The header plan badge was clickable.
+- For sandbox/free plans, clicking the badge opened the pricing modal.
+- For non-sandbox paid plans, clicking the badge opened Account Settings on the Billing tab.
+
+Current MainNav behavior:
+
+- Sandbox/free plans have an explicit Upgrade action in the WorkspaceCard credit row.
+- Non-sandbox paid plans show the workspace plan badge, but the badge is display-only.
+- The WorkspaceCard Settings menu item routes to Account Settings on the Billing tab.
+- Invite Members remains the Members entry, so Settings and Invite Members do not duplicate the same destination.
+
+Open question:
+
+- Confirm whether product still wants the plan badge itself to be clickable, or whether the Settings-to-Billing menu item is the intended MainNav access path.
+- Avoid making the plan badge itself clickable unless the interaction is explicitly approved, because the WorkspaceCard already uses a button to open the workspace menu.
+
+Recommended default:
+
+- Keep sandbox/free behavior as the explicit Upgrade action.
+- Keep the plan badge display-only.
+- Use the WorkspaceCard Settings item as the Billing entry.
