Don't delete downloaded APK
AuroraStore saves the downloaded APKs into the Aurora folder on my SD card. (On my device installation of APKs via AuroraStore doesn't work, but that's not the issue here). When a new version the APK is available, the old version in the Aurora folder is removed: Sometime I want to downgrade to an old versions of an apps, but the file has been deleted.
Please add an option to keep the old APKs, and don't delete them. Preferrably a setting "keep latest n versions" could be added.
