Feature suggestion: automatically scale font size when leaving Full Screen mode
-- For the sake of having screen content intact.
More lengthy: obviously Full Screen mode (FSM) allows for more LINES COLUMNS. Switching back from and to FSM again sometimes is required and leads to useless flickering caused by re-draw or a mess even -- if there're no handler running for SIGWINCH (or it fails to handle things right). The idea is too scale font size in such a way that after switch from FSM user has same geometry of sessions.
