Tabs always on top is not a great choice since it covers up browser tabs, windows, etc. Sometimes the dock does not show even when I hover my mouse at the top edge of the screen. What is really needed is the ability to show/hide objectDock using user configured keyboard shortcut keys (hotkeys).
I agree. This would be a welcome update. As an option, Autohide like Quick launch docks, with an Always on Top option like the Start menu, would also be a welcome addition to the Accessibility options for Tab docks.
