Keep in mind that Lawnchair is buggy and consistently 2 years behind the latest version of Android. I'm using their 12.1 beta, and it still crashes with null pointer exceptions about twice a week. And, on Android 13 and 14, integration you would expect between the recents screen and Lawnchair does not work. These are the gestures you're talking about.

And here we are on the launch of Android 14, with no development of Lawnchair for Android 13 in sight.

I should also point out, these gestures you're mentioning only work on the stock Pixel launcher, the AOSP launcher, and Lawnchair. This is because starting with Android 9, Google baked the recents switcher directly into the launcher app. And, it has to be a system-level app with a special system config that allows the launcher to perform this function.

This is why root is needed for the Quickswitch module. Lawnchair has the code to do this (at least on Android 12), but you have to overwrite a system config to allow Lawnchair's package name to be capable of serving the recents screen.

I just tried on two pixel 3 on A13 side by side and the only difference I can see between using pixel launcher (system) and lawnchair is:

1. When you go back home, pixel launcher adds an unnecessary animation that goes to where the app icon is saved on the home screen.

2. On the system Launcher a short swipe opens the app drawer and to open the recent apps you need a very long swipe

Both are winning points for the custom launcher.

Has Google not fixed this yet? I'm in A10 and use Niagara launcher as my default with Navigation Buttons.

As far as I can tell Lawnchair game been updated in a while. So it's literally 50/50. And no idea if it's still being developed at all.
