Main window

The main window has four parts: the top bar, the notice row, the outputs strip and the status bar. There is no left sidebar.

Top bar

The top bar is 48 px high. It holds the logo, the page tabs and, at the right, the status controls.

Control	What it does
Hot buttons, Sequences, Perimeter, Overlays, Library, Settings	Page tabs with an icon and a label. Perimeter shows only when your plan includes the LED surface. Overlays shows only when your plan includes overlay authoring.
On air	Shows the number of items on air and up to two names. Select it to open a list that groups them as Sequences, Rotations, Hot buttons and Overlays. Select a row to open its page. The list has no stop control.
Venue health	Shows the venue name and a status glyph. Select it to list problems: an output that is not connected, a stream that is lost or stalled, a controller that is disconnected or in error, and a busy GPU. Select a row or Open Patch to open Settings.
License grace chip	Shows when the computer is offline and fewer than 3 days of grace remain. It is amber below 3 days and red below 1 day. Select it to open Configuration → License.
Free plan · Upgrade…	Shows on the Free plan only. Opens Configuration → License.
Live values	Opens the live values of the overlays. It shows only when your plan includes overlay authoring. See Drive an overlay live.
Help	Documentation, Release notes, Open-source notices… and About ArenaDirector.

When the window is narrower than 1500 px, the top bar becomes compact:

The page tabs have less padding.
On air hides the names.
Venue health shortens the venue name.
The license grace chip drops Offline · and shows only the time that remains.
Live values shows only the number of overlays on air.

The notice row is 36 px high and sits under the top bar. It shows one notice at a time, the most urgent first. N more cycles to the next notice.

Notice	Controls
GPU warning	Dismiss. The notice clears by itself after 10 seconds.
Restart to load everything your new plan unlocks	Restart now, Later

The outputs strip is 128 px high and sits above the status bar. It has one tile for each canvas, bus and stream.

Tile state	Look
On air	Green border
Canvas without a screen	Dashed amber border and No screen in this venue
Bus with a missing device	Dashed border and Not connected
Lost stream	Lost chip, dashed border and Fallback on screen

The status bar is 32 px high and sits at the bottom of the window.

Control	What it does
Outputs	Opens and closes the outputs strip. The app remembers the setting. The strip is open by default on windows that are 900 px high or more.
Output chips	While the strip is closed, a chip for each canvas, bus and stream. A green dot marks an output that is playing. A chip with a problem (for example lost · fallback on screen, not connected or no screen) comes first. A playing bus shows its level (for example -12 dB).
Background work chip	Shows the library indexing and processing state. See Manage background processing.
CPU	The load across all processor cores, in percent, with a small meter.
RAM	Memory in use, as a percentage of total memory, with a small meter. Hover over it to see the amount (for example 12.3 GB of 32 GB).
GPU	The GPU load in percent, with a small meter.
Clock	The time of day as HH:mm:ss.

The meters show how close the computer is to its limit. They measure the whole computer, not only ArenaDirector.

Meter	CPU and RAM	GPU
Green	Below 75 %	The GPU has headroom.
Amber	75 % or more	The GPU has little headroom left.
Red with a warning sign	90 % or more	The GPU is at its limit.
