A new proton user with GB of emails from previous system. I have stopped using it as now on proton.

I have setup a folder structure to allow emails to be stored relative to name of folder. The filter moves the messages correctly, but unless I open main folders to see subfolders with new email count, I don't know what emails have been received. I cannot always respond to notification in real-time.

Allowing a filter option to copy messages rather than just move, means I am aware of what has arrived and can read / respond to it, deleting once done as copy in folder.

Alternatively, auto-open folder with new messages when they arrive, so I can just run my eye down the list to deal with new emails. I am having to assess ALL EMAILS which is clumsy.
