Project Stacks

I tried out a different scrolling mechanic for Lumbermill today. In this setup, the left data panel is static so you can always see it, while the project stack scrolls. The columns are linked by a line which signifies the breakpoint for completed/paid projects.

Does this make sense or nah? Would it be something that makes sense without an explanation?

Lumbermill is my latest side project for freelancers.
