A free program for Android, by Braden Farmer.
Taskbar is a tool that can put a start menu and recent apps tray on top of your screen that’s accessible at any time, increasing your productivity and turning your Android tablet (or phone) into a real multitasking machine!
If you use a device with Android, you can download Taskbar from Google Play.
If you use a device with an Android version of less than 6.0, you can download the APK file that will enable Taskbar. Once you’ve installed the app, open it and enable “Desktop mode” (if you’re using a device with Android 10, this is already enabled).
Now, just tick the checkbox and the app will guide you through the setup process.
