Mac and Linux mp3tag support with QT yes/no??

Hi again,

Im not very technical on programming or same but have observed some things. I see VLC and Xnview (xnview mp) have gone the QT user-interface route to extend their products for wishful cross-platform users. I mean:

QT is cross-platform fuly customizable UI
t seems a good future path for mp3tag to take since it has all the most required features already
*Would it really require a full code rewrite of mp3tag from very beginning?
*Beta testers for platforms seem always willing?
*You could always prioritise the Windows compiling & releases first
*How do Mac and Linux users experience use with mp3tag under Wine / Boot Camp
*Hmmm but are there any other compatibility issues that may conflict use
