Spoiler:I have opened PK3s in Slade many, many times so, if I pick "Choose another app"*, Win 10 already knows that I might want to do this:
Spoiler:And I know that far more than one program can be listed because this is what I get when I right-click a PNG (with nothing particularly special done by me to set this up that I am aware of, other than having all these programs installed and in use).
Spoiler:So, does anyone know of a way to get Slade to appear on the "Open with" menu so that I don't have to pick "Open with" and then "Choose another app" every time?
*As a side note, it bothers me that programs on my computer are now called "apps". A fully functioning office suite is not an "app".
And I never want to "Search the store" when opening a file on my computer. Stop it MicroSoft!
