Just looking at Tabbles and it looks like something I might actually buy. However, I have a problem with changing tags. Let’s say I have some music files tagged “Pop”, but I decide it’s not pop but rock.

If I start by untagging “Pop”, then whooops all file disappear and I have to go looking for them to add “Rock” to the tags.

Why not just have tag and untag in the same window? One line for current tags, one line for tags to be added, and one line for tags to be removed. Much simpler.

You could call it “tag/untag files”.
