Action Launcher-style folders
I want to use Microsoft Launcher but the way Action Launcher manages folders is just too good.
The first app inside a folder can (optionally) be launched by single tapping on the folder. The folder is expanded by a swipe gesture.
This use case is really great for primary and secondary apps. Let's say I mainly use Google Maps and sometimes multiple taxi and car sharing apps. They are all inside the "transport" folder, Maps being the forefront and accessible via a single tap. All the transportation apps are logically together, and the other apps are available inside the folder that can be expanded via a swipe down gesture.
Have a look at Action Launcher's implementation.
