Batch Load style
I haven't found a plugin that can do this, so I guess this is a request. I would love to see a plug in that can take all musescore files in a specific folder and add a chosen Style (from the Load style menu) and save the files.
To take this one step further, it would be nice if we could choose which of the style categories (System, Clefs, Accidentials and so on) one would like do load. This would be nice if I were to add the same footer (with copyright information etc.) to many musescore files.
