I found the option to hide the sidebar in the user configuration page. This works fine on my computer.
I have (had) the same option on my phone. The hide sidebar switch was deactivated (although the sidebar hides automatically on the phone), so I was curious what would happen when I activate it.
Nothing happened. So I switched it off again and the switch and it’s explantation immediately disappeared.
Is this normal? Could someone also try it out?
I do unterstand that this switch makes no sense on a mobile, but why is it here at the first place?
