Among other issues, what is awkward about the tag removal is that if you're reworking files with a mixture of different types of tags, or if you're working with files that you've downloaded, it requires manually executing a 'Remove' operation, rather than the simplicity of either:
- removing unwanted tags any time a file is saved
- being able to automate the removal of unwanted tags with an action
I think many people new to Mp3tag expect the behavior of #1, partly because of how the Write options for Mp3g work: any time a change is saved, Mp3tag will automatically create the tags designated in the Write options.
After working with the program for a while and realizing that tag removal is only done manually, users then go looking for #2 as a workaround. If #1 were implemented, an action would be unnecessary. A checkbox in Tools > Options > Tags that could optionally turn on the behavior described in #1 would be sufficient:
[ ] Automatically remove designated tags when saving tags
