Window / Tab capture
A Window / Tab element shows a live feed of a single application window rather than the whole screen. Use it when you want one app on screen and nothing else — a slide deck, a scoreboard app, a browser tab — without the risk of a stray notification or another window appearing.
Add it: Add Element → Window / Tab….
What it can do
- Stream one chosen window live to either deck.
- Transform and position on a canvas via the card's inline Transform controls.
- Stay clean: only that window's contents are shown, even if you switch apps.
When to use it instead of screen capture
| Use Window / Tab when… | Use Screen Capture when… |
|---|---|
| You want only one app visible. | You want the whole desktop. |
| You need to keep working in other windows off‑air. | You're presenting everything on a display. |
On Linux, window capture uses the system's screen‑sharing picker, so you'll choose the window (and may grant permission) the first time.
