But definitely just ask around and look up how to do things you are accustomed to! They even found the AltTab package somehow, even though I couldn't figure out what was missing... MacOS' minimized windows not being the thing that comes up, if they are minimized, but on Windows it will switch to those windows if they are simply behind or if minimized? Even the package they found doesn't exactly say whats going on. I almost never minimize windows on MacOS.... probably for that reason.
It's different to Windows though. If they're looking for something more similar to Windows, maybe Command+H (hide the active app) is a better alternative.
This is an issue on MacOS, a lot of features like this one are not easily discoverable.
And it is a problem now.
