Dropbox Vault Timer Notification and Option to Extend before locking

Hi Guys , Dropbox has been around for years now, I have been using One Drive Private Vault for many years - only reason I switched to Dropbox is because your Vault function is available on Mac Os - For the Love of God you have had so many users Ask you to create a option that allows the user to extend the timer before the vault just closes suddenly , while a user is still working a file! My Lord , all your developers need to do is create a popup banner saying " your vault is about to lock in 1 min ! you want to keep it open for another 5min, 10min or 20min or do you want to lock it right now!.  This will most certainly keep many MS One Drive users from staying, What the heck is the issue and why haven't you given us this option yet . I just Spend $137 dollars on your Dropbox Plus version to be treated with the most frustrating feature - considering a refund !!!1 just get it done developers
