There is no easy way to switch between workspaces
Right now, in dev branch, switching between workspaces is hard, first mouse needs to go to ubuntu button next to the workspaces, clicking the button and last select the desired workspace in the expo. There is no way (without keyboard shortcuts) to quickly switch between workspaces.
A nice feature could be scrolling the mouse wheel in the workspace button to quickly change between workspaces. Another feature is to actual click in the appropriate workspace directly from the switcher (a button divided in 4) and a right click menu with workspaces to select.
