Keep Personal Vault window open until syncing is complete
Moving a large number of files using File Explorer to the Personal Vault will cause File Explorer to crash and will cause sync problems should the Personal Vault window close before syncing is done.
Since syncing time is unpredictable I would like to see an option for Personal Vault to remain open until if finishes syncing, however long that takes (since I can't predict it myself or giving an outlandish amount of time to keep the window open)
