I would not like to have a list of values to choose from, if it means to loose the feature of MP3Tag that shows me every value of a tag that is inside the highlighted files.
As long as there is no way to have both possiblities without interferring I prefer to have this feature much more.
At the moment the genre tag ist the only tag-field in the tag-panel with a predefined (and individually expandable list). Even there I am missing the general behaviour of MP3Tag to show all tag-values that are actually in the highlighted files. Therefore I had to create my own additional genre-field to get this feature with some loss of comfort as a workaround.
Suggestion for Genres
