Following functionality would be great (ex.):
1. Selecting Files or Directory
2. Open Mp3 Editor (Files are shown like in the Renamer PlugIn)
3. Possibility to set tags for one or multiple selectable files
4. Possibility to rename files with help of pattern and MP3 tags
and more
Thanks
MP3 Tag Editor & Renamer
I suggest to use MP3Tag (http://www.mp3tag.de) for these functions. Just put it in the user menu.
