Use Manjaro on Touchscreen


I want to use Manjaro Gnome on a 5 inch touchscreen runned by the Radxa Zero single board computer. The OS itself has a great touch support.
Its cool to switch the workspaces with 3 fingers. Can I change it to switch it with 2 fingers?

The settings App is very good. You can touch scroll and the buttons are in great size to touch them. The other apps that are preinstalled are not so good for a touchscreen. Are there any good Apps who are usable like the settings app? With touch scroll and good touchable buttons.

The control buttons of every window(minimize/maximize, close) are also to small. Is there a good icon library for touchscreens or is there a way to make them bigger?

I use the Gnome Version of “Dev 20220207” from here:
