19.1.2 - Terrible interface! No longer applies character panel changes on the fly.
Typed changes to character panel had been more interactive. As far back as CS6 changing text size or leading via the panel was interactive when typed. Now it's only interactive if you slide with the mouse, but awkwardly, and not at all if you type in a size afterwards. Leading changes don't apply by clicking back to document window, they now need a enter/return to apply, and there's no preview/interactivity. What a waste of time to have to hit return after a text leading change...and with no preview unless you slide. If you want specific numerical size/leading, the slider isn't useful. This is either a bug or a dramatic regression.
