In this answer in Stack Overflow it says that it’s impossible to edit the recent files list.
However this answer and my following actions doing exactly as the Forum Post suggests prove that it indeed can be done. Thus I’ve posted an answer on SO, as the current comments are wrong.
If anyone feels like posting a comment or answer for Windows and other versions of ST, or just checking I haven’t got anything wrong, that’d be great. Hopefully a quick one, it’ll take someone a minute just to read through my post maybe…
Cheers folks
Ps I wish there was a purple rabbit emoji
