Hopefully others will jump in here with their opinions as well, but I will start. I was not a fan of the upgrade. I bought it when it was first released. When I started using it, I hated it. I have grown to like it now. Some things that I like is the rotation in foundation printing and when coloring blocks, if you go back and remove a seam the colors stay put and are not shuffled. There are several other features that make it easier to work with such as in the Print Foundation dialogue the grouped pieces are colored.
I find the new interface cluttered looking, however, and the pane that has the tools in them is large. You can choose in properties to have smaller tools or to dock the pane to either the right or the left but I have not found a setting in properties to make it smaller. I am now comfortable where everything is and for the most part am glad I went ahead and did the update as a lot of what I do is paper piecing.
Back to EQ8 Upgrade - It is all about the $$ in my mind. While the upgrade is nice, 7 is still a good program with a few workarounds. When I used EQ7 exclusively, I found (as you have noted) that the program printed the blocks the same orientation as they are shown in the quilt. What I did to get around that is to create a second quilt with identical sized blocks. If my real quilt was on point, I often found the foundation spread across four pages.So, I created another smaller quilt horizontally and placed my blocks in that quilt and printed from there. Then before I printed I could change the groupings so that they were smaller or move them around to minimize the amount of taping. Then, for the most part, the groups were straight on the page and not too large.
While I did not find a video,if you go to the page as if to purchase the update,

then click on the features tab half way down that page, all the new features are listed there. Good luck with your decision.
