The cancel button on the save all dialogue is kind of non intuitive and should be renamed to Yes, don't ask again.
Yes, while the box says exactly what the cancel button does, I think it's function can be made more descriptive by renaming it to say Yes, don't ask again.
Background of this is, the save and save-all button are right next to each other, so a misclick is guaranteed to happen at some point. When that happens I assume most people don't read what the dialogue box says but just hit the cancel button because essentially everywhere cancel means don't do whatever I just clicked. Renaming that button to Yes, don't ask again most likely causes people to hit no instead.
