Glad you asked.
Let’s start with QuickStar, I used this to remove icons from the status bar. I prefer having a clean status bar... I only use Cellular, Wifi and Battery Icon. I even remove the battery percentage and time, I can swipe down to get that information from Notification Center.
Then there’s MultiStar, I feel like this is a must for Galaxy Fold... primarily because Samsung hasn’t really fulfilled tablet UI and I think this helps in that aspect. I mostly rely on Enabling MultiWindow for all apps and Multi-Window Screen zoom. The Multi-Window Screen zoom helps for when in pop-up action to view more content. There’s plenty more features to MultiStar, but I don’t really rely on too many options though.
And then there’s HomeUp, I use this to change my Home Screen... I can add more app grids to it for more apps and add a blur to the App Tray. Then there’s the PopUp (app) folder, you can change how that looks as well. Samsung released this Share Manager feature under HomeUp about a month or two ago. It helps to customize the share sheet... makes it less convoluted.
There’s plenty of other modules under GoodLock to use.. but these modules that I personally use. And there’s the Family section under GoodLock, but those modules are standalone apps.. like One Hand Operations+ & Sound Assistant (both are a must).
