I switched from WIndows to Debian a week ago. I’m used to controling volume with 4 finger gesture. KDE plasma didn’t have that option. 4 finger swipe was bound to desktop switching on KDE plasma.
I decided to make a daemon called FingerSwipe to control Volume with 3 fingers instead of overriding the default 4 finger gesture.
FingerSwipe is a service that runs automatically on each login of the system.
Here is the github repo of the daemon. Go through the README.md file for instructions on installation. FingerSwipe | Github
