I would like to suggest the following function as very useful for an improved sense of security with the master password. The master password would have to be given a defined period of validity in a setup. After this time, e.g. 10 minutes, you have to enter the master password again when requested. At the moment it is valid for the entire duration of a browser session.
I hope that I have expressed myself clearly and other users feel the same way as I do.
So long
