Yep you read that right, we’ve decided to throw the lever and go Wayland by default! The three remaining showstoppers are in the process of being fixed and we expect them to be done soon̵…
The double-click speed setting returns, and now lives on System Settings’ General Behavior page. Before you ask why it’s not on the mouse Page, it’s because it affects touchpads too and that has its own page, and duplicating the setting on both pages seemed messy and ugly
As long as the value is synced, I can't imagine how it would be bad to have in both pages; especially since that's where a user would expect to see it.
There's nothing wrong with multiple ways to find a common setting
I think the best solution is to have a... Link? To the general setting.
Having duplicated settings across multiple settings page is something that I think is an issue. Cause it isn't obvious to the user if the setting is actually shared between the two pages or if it has two different options with the same name. It also doubles cognitive load to the user, as if they have a Touchpad and Mouse they need to remember both pages have the same setting.
A link is more of a way for the designers to tell the user "Hey, we know what you are trying to find, but it is in another place"
