> another overlooked feature is that it now keeps track of its state and maintains all the unsaved files that are open in it, allowing me to use it as a momentary place to jot down things that I want to remember but that I don't want to save in a txt file.

There are plenty of apps that do exactly this. Sublime was the best of them that I know.

Notepad was great for the opposite reason. It is ephemeral. I can use it as a scratch pad for passwords and what not, with the comfortable knowledge that it’s all cleared away next reboot.

You can bring classic notepad back, it’s still there, so that’s what I do.
