Refresh metapane

I have button to add title to mp3 like SetAttr META "Title:test".
If metapane is open and I clic button, metapane is not refresh.
Can you add autorefresh to this command or add new command to refresh metapane like Go REFRESH=metapane.

The panel already does detect external changes to the currently loaded files and refreshes automatically. But what it doesn't currently notice is if the change is done via a "safe save" (make a copy of the file, modify the copy, rename the original file, rename the new file, ...).

We'll improve this in the next update.
