The new UI is an improvement, however, it is clearly designed for horizontal scrolling packages such as Storyline and Captivate and does not take into account vertical scrolling packages such as Rise and Evolve.
If scrolling too far down, even when in full screen, the content goes off screen to show the lesson summary. Full screen content should be fixed in place with no chance to scroll too far pushing content off screen.
Additional customisation to account for vertical scrolling type content versus horizontal would also be beneficial.
