iFiling has been a big issue in this game pretty much ever since its release.
I still remember the video tutorials on how to get the iFile app through Cydia.
Its extremely easy to iFile people now but one weakness for all iFilers however is one setting.
Cache Files which is in the General settings.

It would be game-changing to add a feature to have Cache Files disabled for some certain files.
All it'd have to take is to modify the Save Cache script a tiny bit to exclude saving files under "era_player_custom_graalYOURID" and them bam, the iFilers are all gone.
