Confirmation. I just tried disabling Trebuchet and a warning told me I couldn’t uninstall it as it’s a system app part of the /e/OS. In effect, it disables the recent apps button when turned off, so I re-enabled it with App Manager. BTW App Manager was not too happy with one or two of Trebuchet’s activities as it had access to the phone and could read external storage, so I disabled these functions as they seemed unnecessary activities for a launcher.
In fact I replaced Bliss with Omega as my launcher and am very happy with it. Much more adaptable than Bliss.
