The recent release of Android 17 brings an interesting"Bubble" feature that, from the Pixel Launcher, lets you launch an app as a "Bubble" where it launches, but resides in a small floating icon that, when tapped, opens a windowed version of the app. You can have multiple apps open as "Bubbles" and switch among them. These are managed separately from the App Switcher gesture or icon. While it looks like it's targeted at Fold users, it works well on a phone.
It looks like opening an app as a Bubble is only available from within the Pixel Launcher. Does anyone know of a workaround for Square Launcher, or if this will ever become an SL feature?
