In the process of trying to eliminate as much conflict as possible, I decided to try experimenting with one folder using the computers (models like laptop, Easy, Expensive, Sunair, etc) and a complete set of files that all of the computers can use. Originally, I stated that if you wanted all of the models, you would need to create 4 separate folders and install them into their own folders to prevent conflicts.
I know this response comes a tad late, but I just wanted to mention how I've always felt that with a little care, these computers could all work from a single folder. For files with the same name, it was a bit of a hassle to figure out which one to use, but I could get it to work.
The work that you did to streamline it, makes things a lot easier, though. Great job, thanks again.
Currently, I'm working to make it so that interest calculations are only made on livable lots, and only for sims that are actually members of the currently active family. Because for those who play without the Community Time Project mod, your sims gaining interest on their deposits while not at their own home lot... that's just nasty, and can lead to extreme results. And the same goes, of course, for sims from other households visiting your current family, or appearing at the comm lot you're visiting...
