Revisit scrolling settings, Stretch edition
It seems that 3.0~alpha1 does natural scrolling by default, while we decided two years ago (#7779 (closed)) to not do that.
Our custom settings live in
but the way we do it may be obsolete in feature/stretch, as these
settings have moved from
org/gnome/desktop/peripherals/touchpad. Which suggests that on
Stretch, GNOME now enables natural scrolling by default.
We should update our survey of what other OS’es do with more recent info + info about scrolling settings, and decide how we want Tails 3.0 to behave.
During our December monthly meeting  we discussed this and decided to rather drop our customisation (as most of the OS are doing natural scrolling now) and let GNOME+libinput do what they think is best, i.e. natural scrolling in most cases.
This way we keep reducing our delta with upstream.
