JJJ,
besides hypothesis, do you have concrete bugs that you are aware that are present in new picker, which are not in any of the old pickers?
If yes, kindly list them. Obviously if all other pickers will be removed, it will have to go through Pre-release testing stage.

Again, I am kindly asking anybody who is against the idea of removing previous pickers, to be very specific and support their views with concrete examples of workflow issues/bugs that are present in new MTP Library that are absent from other pickers. We are not talking about a book or a painting here, but very specific part of software. I want PGMusic to be aware of the specific reasons, to why people think they should leave huge chunk of code in their software, which seems obsolete.
