And, for reference, my actual setup, with @jcn363's footer-killing patch

.
Code:
Dec 19 20:31:41 nickel: ( 99.991 @ 0x553010 / ui.debug) draw widget: 46 QStackedWidget QRect(0,11 1080x1429)
Dec 19 20:31:41 nickel: ( 99.991 @ 0x553010 / ui.debug) ===> parent widget: AbstractMainWindow
Dec 19 20:31:41 nickel: ( 100.036 @ 0x553010 / ui.debug) draw widget: 46 QFrame QRect(0,55 1080x1385)
Dec 19 20:31:41 nickel: ( 100.036 @ 0x553010 / ui.debug) ===> parent widget: ReadingView
(Which confirms the 44px we got back from the footer, compared to
#72).
