This extension is really a good job!
Now I want to reorder the subfolders list... I'm using another extension (Manually sort folders 1.1) which is very functional, but only when the subfolders are not promoted... when I promote, the order jumps back to the default used by Thunderbird.
Is there a way to resolve this?

Thanks

Fulvio
