Fullscreen Detection

ExtraDock detects when an app enters fullscreen and automatically hides docks on that screen.

How it works

When a fullscreen app is active on a display, docks assigned to that display hide automatically. Docks on other screens are unaffected. When you exit fullscreen, the docks reappear.

Detection is per-screen — only the dock on the same screen as the fullscreen app hides.

Enabling and disabling

Fullscreen hiding is on by default for all docks.

To disable it for a specific dock:

• Right-click the dock → Don’t Hide on Fullscreen

• Management window → Properties → Behavior → Hide on Fullscreen
