4.15 Blendspace Editor changes

Just installed 4.15 and was mucking around and realized the Blendspace editor was completely different…
And I have no idea how to use it lol
I didn’t try very long mind you… but it was enough for me to try to find something that explains its changes more in depth… and can’t find much.
Anyone out there have some tutorial page/video that explains the new way to do things?

Thanks

EDIT

I realize now that the editor is kind of the same as it was, only laid out horizontally.
Just need to get used to the new layout I suppose!
