Agreed. I understand that Proko 2.0 is aiming for a structure closer to a platform like Udemy, but unfortunately it adds a lot of visual clutter in the process. The more simple original chronological layout was much better for a quick overview and finding specific lessions since it was all laid out on a single scrolling page. My main criticism of 2.0 is that the lessons is crammed into an absolutely *tiny* window in the upper right corner while the community section takes up most of the real estate. Having the ability to comment and ask questions is fantastic but for the bulk of study sessions it adds irrelevant clutter and space that could be better used for the actual content. In conclusion; I'd love to be able to switch back to the old view, or atleast increase the small content window. It would be terrific if the community/comment section could be turned on and off for bought content.

@huarui chen You are able to open the lessons and 3D models in separate tabs or windows to watch them at the same time. You can do this by right-clicking and selecting the option you prefer. I hope this helps!
