Every time we generate a script action in mp3tag it is saved in a list and can be selected for re-use. But we often create one-off actions which stay there making the list messy after a while.
Where are those actions stored and can they be edited and/or removed???
Which actions are you referring to?
Sorry, forgot to specify and didn't know how to edit after the fact...
Talking about the scripts (tag lines) that are generated and saved every time you use the convert tool...
There is this small ▸ button next to the format string fields, which shows a menu with options to remove the current or all items from the history.
