How can I raise the title bar above the tab bar in TB57.0b1 on a Mac (OS 10.10.5)? Now they overlap! This problem just appeared with the upgrade to TB 57, with the advent of the square tabs. (See attached image, where the window title "Inbox" is overlapped by a tab.) With the title bar in its own vertical position (above the tabs), it's easier to drag the window without interfering with the tabs, and easier to read both the window title and the name of the (otherwise overlapping) tab. There's long been a fix for this in Firefox: by going to "Customize," a clickable option appears on the lower-left corner of the window, allowing one to create a separate (raised) title bar. No such option appears to be available in TB. Can I fix this by making a change in the "config" editor?
