This has already been done on desktop, but hasn’t been added on any mobile platform as I’ve yet seen.
On mobile, the button to “DELETE AND NEVER ASK AGAIN” is dangerously close to “DELETE”. I fear I may at some point accidentally bump the button to never ask again and may then accidentally delete an important file later (thankfully I use the .trash folder option so I can easily fix such a mistake).
But on desktop, there is a CHECKBOX for NEVER ASK AGAIN that is on the opposite end of the dialog.
Please add the checkbox feature to mobile and move it far enough away where I don’t accidentally bump it. Thanks.
