NEW IN RISE: Timeline Block

Dear Articulate Staff,
I was told that it is planned like that not to show the line connecting the next block in a timleline, until it is rendered - but this causes usability issues. Maybe you could reconsider and render the line of the next block together with the current block, so that the line hints that there is something more to come?

Here is the screenshot that confirms the problematics:
one of the blocks in the timeline contains text and video.
The user scrolls slowly through the text while reading (and thus the next block and the connecting line do not appear -as only a fast intense mouse movement causes the line to appear, and the slow one does not -- , so it looks like the last block in the timeline though it is not), 
Then the user watches the video and thinks this was all! They do not have a visual hint that they need to scroll more, especially if they view the course first time -- so they just miss the rest of the material.

We prefer the self-explanatory approach, where you do not have to say explicitly to a user to scroll down , and anyway a user can forget this as they proceed.

Maybe you could reconsider and render the line to the next block already when the current is displayed? People get confused.
Many thanks.
