Hi muenchhausen,
feel free to revive the addon as Clarity revived or the original name
I had no time to test or update it.
But you should please strip the embedded libraries and add them to the txt file as ## DependsOn: LibAddonMenu-2.0>=31 + strip any LibStub calls.
Here is my last vesion I had used, maybeyou can setup yours on it:
Clarity 1.0.6 Baertram - Stripped LibStub and updated API + library versions
