It says in the forums/FAQs that m4a files are taggable, and yet every time I try to change my track numbers from 1,2,3,4 to 01,02,03,04 they come back as 1,2,3,4, Do I need a plug in or what?

Mp3tag does not support plug-ins.
And M4A files do not support leading zeros for track numbers.
Trying searching the forums: M4A track.
Start here: [Not possible to save track numbers with leading zero in m4a](https://community.mp3tag.de/t/not-possible-to-save-track-numbers-with-leading-zero-in-m4a/49664)

Thank you @ryerman I guess that explains it all.
