Folder "Delete All"

Outlook has a “Delete All” right-click option for a mail folder that keeps the folder intact but deletes all of the mail within the folder. Mailspring only allows for total deletion of the folder.

To be honest, this is the only item that has kept me from moving totally to Mailspring from Outlook as I have a number of folders that I filter junk mail into that I routinely blow away everything in it after quickly perusing it.
