This is the first submenu you see, when you enter this section of the MCCC UI, Use Auto-Save.
Of course, I'm going to Enable Autosave. It's one of my favorite things MCCC offers. (The first of many I'll be pointing out along the way.)
(Data taken from MCCC 4.0.0 and Sims 4 version 1.37.35)
MCCC has two menu styles, shown above, with buttons that show both the [Default] and >Selected options, and below, with a text entry field.
Current Save Number is controlled by MCCC.
I don't personally see any reason to change the Hex setting, the Interval Amount, or Show Confirmation.
Interval Type I change to Sim Hour. I'm such an avid saver, that's the only one I can use and see something actually happen.
Each of the different interval types are detailed in the settings table. See the bottom of this post for a screenshot and link to their page on Deaderpool's Tumblr.
Max Save Number (see 2nd picture above) I set on 10. I'm a HUGE fan of backups and extra copies.
Here's how a file saved by MCCC looks in your /saves folder:
Between that setting and the Sim-Hourly saves, it's rare for me to lose more than an hour's worth of gameplay, if I decide to reload because something happened that I wasn't thrilled with.
Name? MC Save works fine. But I changed mine to EG Save, just because I could.
