Octopi launcher is what I switched to recently. Tried a lot and it’s the only one that felt really ok to fully replace Nova. For now there is the home grid that need to be a little bit of work. Nothing major, juste better shortcuts positions. Dev is active and said it was in progress.

I am watching Einstein Launcher hoping it could be ok, and waiting for lawnchair to implement (if they either do) swiping up on shortcuts and folders.

Not sure about the new app. For now I switched to SyncthingTray.
