There’s probably a way to turn it off but I hate how it auto opens the last file now.
The addition of tabs to Notepad has made me stop using it entirely. My entire workflow around it was having separate windows for each document that I could move and close freely. Having an all-in-one-place Notepad filled with the ghosts of API tokens past is precisely the opposite of what I needed.
Strange. Microsoft seems to struggle with the fact that they named it "Notepad" and some subset of users took this to heart and used it as a note pad, but due to backwards compatibility concerns it must never save rich text formatted files, else it could cause confusing data loss scenarios for users just trying to edit config files. Hence, the odd combination of LLM features added to a text editor that will never support rich text or rendered markdown.
