Open and close folders automatically

When we move some board from a folder to one other, all the folders we pass by will open and stay open even after we are gone… I work with lot of folders and would spend lot of time closing the folders one by one each time I move a board… Would be great to have them close automatically when we just go over them without dropping anything in them…

I would also love for this to be implemented. Just hover over a folder for a second before it opens.

Additionally, since we also have a lot of folders, it would be nice if after loging in, all folders would be closed. At the moment ever single one is opened, no matter if they were closed or not before loging out.
Our main boards and dashboards are not in folders, so we don’t need to have every folder open when logging in.
