Is there some additional window manager or other tool installed on MacOS?
No, other than the normal option of having multiple desktops (spaces) available - which I use. Generally allocating a single app to a desktop - keeps everything tidy.
However, currently, VS is on the same desktop as Safari.
Command+TAB is one easy way to get to another app (you can use Mission Control - again, part of the OS and not a separate app as such), the OS just displays a horizontal panel of apps - click on one to go there.
