I want to try out some interesting KDE Plasma themes, but it warns me beforehand that it will replace all my existing settings which took me a long time to set up, and I strongly suspect that everything will change and not allow me to revert back to what I had.
How do I actually save the current theme so that I can just revert back with one click, by clicking “My theme” in the list of themes? I don’t understand why this feature appears to be missing. It prevents me from daring to try themes.
