This option does exist in Ubuntu Dock. It's just disabled by default. It can be activated using Dconf Editor. Set the parameter 'org.gnome.shell.extensions.dash-to-dock' to be equal to 'cycle-windows'. It can also be easily done by running this command:
gsettings set org.gnome.shell.extensions.dash-to-dock scroll-action 'cycle-windows' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886075 Title: Switch app windows using mouse wheel over dock icon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1886075/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
