I use softwares, that opens projects, which take some time to open, say for e.g. Unity Editor, Visual Studio etc. With the reopen windows thing, it just launches the Unity Hub, and Visual Studio Launcher. It doesn't actually open the apps to the state I was expecting, hence wasting time. I was looking for Windows like Hibernate, coz I don't need to keep it powered. Imagine, being able to resume from exact previous state, all undo history maintained, clipboard state, everything as was left previously, This is how it worked on windows.
