Tap the small gray handle once to reveal the PM logo, then tap the logo to open the menu. Use the switches inside the panel to enable or disable options—your settings are saved automatically.
The menu closes when you tap outside it, press Back, tap the X, or drag the PM bubble. The bubble retracts after four seconds only while the menu is closed.
Changing an option should keep the menu open. If it closes while you’re tapping a switch inside the panel, that isn’t expected—please share a short recording and your Android version.
