Hi there,
my documents root folder (active: recent, not name) sorts the older folders (of 2019) at the beginning and the newest at the bottom. I think, with the option “recent” activated it should be reverse. But there is no button/function to fix it. Or do you have a workaround?
Seems that nobody has an idea? 
Is it a bug?
My “Recent” does not show the recently accessed folders either.
Seems, that this is a permanent bug and the Marginnote developers don’t care.
