Scenario Tab Bar
The Scenario Tab Bar sits below the Top Bar and lets you work with several scenarios at the same time. Each open scenario has its own tab, in the style of browser tabs.
| Control | Function |
|---|---|
| Folder button (▾) | Choose your scenarios folder. The menu starts with Browse for folder… followed by up to 5 recently-used folders (most recent first); the current folder is ticked and folders that no longer exist are marked as not found. Shown in the desktop app only. |
| Home | Returns to the start screen (no scenario shown). |
| Back / Forward | Steps back and forward through the places you looked at (scenario, object, viewer and date). Shortcuts: Alt+Left and Alt+Right. |
| Find anything | Opens a search box over objects, scenarios and viewers. Shortcut: Ctrl+P. |
| Scenario tabs | Each tab is an open scenario. Click a tab to make it active. A dot marks a scenario held in memory; a ring and a small reload icon mark a scenario that must be reloaded when clicked. A badge shows the scenario type (HIST, BCAH or SIMU, the same badges as the Scenarios tree). |
| × (close) | Closes that scenario tab. Closing the selected tab returns to the start screen. |
| + (new tab) | Opens a new empty scenario tab; then pick a scenario in the Scenarios tree. Stays at the right edge of the tab strip. |
| N/3 counter | Shows how many scenarios are held in memory out of the number allowed. It changes colour when all slots are in use. |
| Scenario Check | Shows problems found in the open scenario's files. Only shown when Settings → Dashboard → Show Scenario Check button is on (default: off). |
| Series Summary | Opens or closes Series Summary. Always available, also with no scenario open. |
Shared iSnaps that you open also appear as tabs after the scenario tabs.
Reordering Tabs
Tabs can be dragged to reorder them. You can also move the active tab with Ctrl+Shift+PageUp (move left) and Ctrl+Shift+PageDown (move right).
Tab Right-Click Menu
Right-click a scenario tab (or press Shift+F10 on a focused tab) for:
- Close, Close others, Close all, Close to the right
- Copy folder path
- Open folder in Explorer (desktop app only)
In-Memory Scenario Slots
Dashboard holds open scenarios in memory so you can switch between them instantly. The N/3 counter shows how many of your in-memory slots are in use.
What "held in memory" means: A scenario held in memory has its results already loaded. Switching to it is instant — no reload from disk.
When a slot is needed for a new scenario: When all slots are full and you open another scenario, Dashboard asks first:
"Opening [new scenario name] will unload [oldest scenario] from memory."
Choose Proceed to continue or Cancel to keep things as they are.
What happens to the unloaded scenario's tab: By default its tab is closed. If you turn off Settings → Dashboard → Close tabs beyond N pre-loaded, the tab stays in the tab bar and the scenario reloads from disk when you click it.
Is work lost? No. Unloading only releases the results from memory. Reloading re-reads the scenario's output files from disk; nothing is re-simulated.
Changing the slot count: The default is 3. Change it in Settings → Dashboard → Preloaded scenarios (1 to 5). The new value takes effect the next time iPool starts; the desktop app offers a Restart now button. Settings of 4 or more show a warning that the Suite may hang or crash.
Missing Scenario Folder
If the open scenario's folder has been moved, renamed, or deleted, a warning panel appears in the scenario area with the message "This scenario's folder is no longer at [path]". Use Find it… to select the new location, or Close to dismiss.
