Everyone in my company uses a company provided macbook, but I use my own Windows Desktop. When presenting stuff to my boss, I'll use windows shortcuts for tiling windows (Win + Arrow keys) and my boss said that's the one feature he thinks is missing from macOS that Windows is really good at
Another bit is that Explorer's Save File modal does autocomplete for file names, which has the side effect of immediately alerting you that a file name is already in use before you submit, but is also massively helpful when you're naming consecutive downloads with a naming pattern.
That latter case would be supercharged if Finder supported this on macOS as the global text edit bindings are more ergonomic for me than those shared between Windows and Linux.
