This button could even have a variable that you can edit to your choice, as Don't ask for [X] amount of levels. So it isn't a "Don't ask ever again" button. This presents the problem of accidentally typing "99" or something, and you'd never be able to evolve it. Only a fixed amount such as 5 or 10 would be nice to prevent this. Thoughts?

Everstone exists, doing this exact function when equipped, but I understand it may be annoying to occupy the item slot just for this to not happen. I'd suggest a tickable box in the options menu preventing evolution windows to pop when ticked.

In the options menu would be a great idea, didn't even think about that! It's helpful for newer peeps like me because I can't trade yet to get an Everstone from someone else. But even then, the item slot would be a hassle yeah.
