Yeah you’re right… my bad 
Actually I don’t like that top bar taking up space either (because of the way I have my inspector setup with the EQ curve, Inserts, and Channel all showing), so what I do is I tuck the top bar underneath the Cubase menu bar. The only drawback is you get a vertical bar on the right, but thats not really a big deal for me since horizontal space if much less important than vertical space.
*edit: uploaded a screenshot of top bar tucked underneath the menu bar
