Thank you, very nice of you to say.
Sadly, we can't currently do that. The mod primarily deals with adding content through variations of dialogue for existing assets(images), and trying to match those assets, from the original game and Saddog hasn't really implemented that part in the main game as of yet.
He did implement alternate outfits for the three main girls. You can either set it so you buy those outfit manually, or can set if so they buy the outfits themselves as you reach certain requirements for each girls. Those requirements are the same as if you were purchasing them for yourself, so as they are listed in the shopping app on your phone, just after you reached those requirements, you just need to have lunch with them at noon and they will ask to meet with you afterwards to show you their new outfits.
You can find a list of scenes based on location in the game under the help section on the phone, by clicking on the red box icon "What's in the box?!". That brings up the in-game mod walkthrough. There is a legend at the top of the mod walkthrough that shows you what to look for regarding custom scenes. It also lists how to unlock them as well. It's not perfect, but it's what I have for now.
The majority of the side characters sadly don't have major events. They are introduced and have minor events to increase stats, so I have included their stat manipulation options in the cheat menu, in case we get more content with them in the future. There are a couple events with Miranda in the basement. And I am adding a mod event with Kate with my next update.
You're welcome. The mod has been an ongoing personal project for a few years now, I'm glad you have found it and are enjoying it so far.
Oh, and you can also check the change logs as well on the OP to see the changes and scene additions for the mod over time to get a good idea about what as been added to the mod too.
