This is great! I use Notepad++ for a lot of first drafts. I used to use a Tandy 100 (yes, that ancient “laptop”) because it ran on 6 AA batteries, displayed only 8 lines of text at a time, had a text editor with no formatting, and maybe held about 11 pages of text at a time. But damn if it wasn’t awesome to just sit…

Yeah, a seriously valuable disclaimer for all the combat-ready professional swordsmen watching.
