Can I stop the Dropbox Vault from automatically closing?

I understand why there would be a Default setting to maintain security but surely there should be a setting that allows for adjustment. I have a situation where there is a lot of thought required before updating a folder in the Vault so it can easily go for 20 minutes between input. It is really disruptive to return to the file with your new thoughts only to have to think about your login code again and again. Is there any progress in updating that function?
