Latest Windows Insider build makes a major upgrade to, uh… Notepad
Found on Ars Technica on Tuesday, 11 December 2018

Notepad already received a significant update in the recent October 2018 Update: Microsoft added support for files with Unix-style line endings.
Notepad is also going to support a convention that's literally decades old: when the currently loaded file has been modified, an asterisk will be shown in the title bar.
Too bad, for a short moment there was hope that it would support more than one undo step.
