Please entertain redefining Zune as cross-platform GUI toolkit.
I can entertain redefining my right ear as my left leg.... probraly very entertaining but won't get me very far ....
Zune is what it is and IF it wants to become a cross-platform GUI toolkit of it's own merit it would need to drop mimiking MUI (read zunemaster.libtrary ZUNEM_ and ZUNEA instead of MUI this and that).
Problem is there would be 0.0 Zune SW at that moment.....
Mind setting up ZUNE-MUI and ZUNE-ZUNE in parallel under AROS and developing ZUNE-ZUNE further independently from MUI might make sense and in this scenario porting ZUNE-ZUNE to MorphOS would atleast not be completly pointless.
Edit:
In a way you are proposing Wine as a cross-platform-API for *nix and Win and are then demanding that Windows should be adapted to quirks&shortcomings of Wine......
