Just discovered this on IzzyOnDroid. Nice.
First installed on crDroid Android 8. Once installed I couldn't figure out what do as there was no launcher icon.
Then installed it on Havoc Pie ROM. Received an Xposed/LSPosed notification. Ah, now I saw. That crDroid does not have Xposed. Description/README does not mention it is an Xposed module. Might want to make that clear. Thought it was a standalone utility.
Tests.
HavocOS, Android 9: Not working. The Advanced drop-down is still present.
/e/OS (LOS-based), Android 10: Works.
crDroid, Android 11: Works.
/e/OS, Android 11: Works.
All above using LSPosed 1.8.6.
The device with crDroid Oreo is a multibooter so I'll test on the other ROMs shortly.
