[Request] Unofficial System(less) 7.0/7.1 Support

[JERW86]

Hello,

I noticed that some of InstallerOpt features do not work with the recently released Unoffical Xposed 7.0/7.1

The features that I tried but don't work are:
-Install apk with mismatch signatures
-Downgrade apps
-Unknown apps install prompt. (It just shows a blank window).

I have attached logs and screenshots for system and systemless unofficial xposed. I hope you will consider adding this support.

Official Xposed for Nougat is now available. Will you be updating this module, @afxefx?
