Gräßlin: Next Generation Klipper

Right! Klipper is configurable with a default chosen with the less advanced end user in mind. Both paste bufffers being saved might annoy, too much churn, then you configure Klipper by check box to ignore 'selection'.

This kind of user preference change, is exactly kind of thing that let's you be "at home" or avoid undesirable behaviour like having pass/key info saved into a temporary file, but can complicate things for writers of HOWTOs and tutorials.

I really try and live with system defaults for quite a long while and adjust, before burning time on tweaking.
