And @phuongn, I'm guessing you set all of these options to disabling wrap-around, right?

Agree! Updated 🙂

Ok! I updated the string, it's now "Enable desktop navigation wraps around"

Correct the erroneous logic for determining the next and previous desktop index

Good spot! I was too careless there. The erroneous logic for determining the next and previous desktop index is now corrected.

Currently there is already "Desktop navigation wraps around" option for Virtual Desktops, which serve exact same purpose as this patch, but only for keyboard shortcut.
I used "Page navigation wraps around" because the pager can be used to control either Desktop or Activity, so I used "Page" instead of "Desktop" and keep the rest of the string similar to existing option from Virtual Desktops settings. Using other strings might confuse user of what this does.

Hi, it's just the default desktop changing effect. Activated by scrolling with the cursor hovering on the pager. I haven't changed the effect, just added an option to toggle page wrapping

Use standard min max functions to make code more readable for desktopswitch no-wrap option

Utilize Math methods (min, max) to make the code more readable

I couldn't find an easy way to access KWindowSystem config from there.
On the other hand, I personally prefer wrapping when using keyboard shortcut and no wrapping when using mouse or touchpad gesture. I figured some people might need the same flexibility.
