More User Friendly for Architects

I've recently started building up a wall and it became frustrating not knowing which was the last wall that I've added resources to. Sometimes I opened up the build for the wrong wall thinking that was the last wall that I've interacted with. What I'm trying to say is...

Have some kind of indication that a plan has resources in its build. It could be a glow affect or a ground cursor, whatever would make it more user friendly for an architect. It's just too difficult to keep track of each plan. A plan that is empty should look different than a plan that just got resources added to it.
