Hey, so I know you can tap on a dock icon to launch the app, but when the dock is more than full and requires scrolling to shift the icons, this still cannot be done with the touch screen, based on docks I have tested. I tried the built in docks in Gnome on Pop, Ubuntu, and also Plank. None respond to an attempted drag via the touch screen.
Are there any less widely known ones that do? Are there any plans to bring this functionality to the dock in Gnome?
Sorry. If there is a keyboard key or other input event to scroll it, you could set a touchscreen gesture to emulate that input?
Standard scroll. Like with a mouse wheel or two finger swipe or edge swipe on a touchpad.
