There is a tracking system for Homeless, Jobless and no rec plot. You have to go into the holotape tools-> tracking -> people. For some reason these tools are not in mcm. The tracking adds quest markers which I think is better than the old 'colored' settlers that were hiding or stuck somewhere.
Also note that for some reason the settlers assigned to the 'occupant' slot of the new multiRes plots show up as homeless when tracked or hit with the Vit-o-matic. I set the extra settler information popup window to a hotkey. (MCM) This way when you are tracking homeless, a quick hit of the hotkey will verify they are indeed homeless.
I also miss the SS1 tools and reports. I assume when things settle down on the hotfixing, we should start seeing these things ported over. I've been posting my wants (when I remember) over in the suggestions forum.
