Not possible to use Trebuchet / Launcher3 as default launcher / home app

• /e/ version: 0.21 Q & R, probably others
• Device model(s): not device specific
• Device rooted: no

The problem

Trebuchet / Launcher3 cannot be used as home app / launcher. It is present in the ROM, but the ability to use it as home app launcher is disabled. Because it is already present - but not usable - it is not possible to install a working version from F-Droid

Steps to reproduce

1. In F-Droid - search for Launcher3. Open the found result. It says version 10 of the app is already installed
2. Settings | Apps and notifications | Default apps | Home app. Neither Launcher3 nor Trebuchet is in the list of allowed home apps

Technical informations

Apparently it is needed in the ROM otherwise some home screes features do not work. If you disable Trbuchet using adb then the 'recents' button in Bliss launcher does not work

But the 'Use as home screen' intent has been disabled so the installed version cannot be used

Solutions

Workaround

It may be possible, to disable it using ad, and immediately install the F-Droid version.

Possible fixes

Either

1. Add the 'recents' fucntionality in the Bliss code so Trebuchet is not neededas part of the ROM Or
2. Enable the 'Use as home screen' intent for Trebuchet in the build
