I discovered a gem of a Mod on MTS that fixed up the subhood UI and allows a custom shopping district to be started without starting the default one which is loaded with sims.You can also start a custom downtown with your own lots for outings.I tried starting a shopping district in Strangetown and was able to get a custom one started.That helps when your main district is starting to get full and you need more room for new families and for the kids who've grown up and want to move out.
