Good points, @eskela. I tend to set to re-prompt the master password for items with sensitive (banking/financing) data, for example. Credit cards, bank accounts and so on.
It’s also a good idea to re-prompt the master password with a fingerprint reader anywhere (desktop/mobile/browser).
Optionally to just ask for the fingerprint instead of the master password. (Which is a feature I’ll ask for very soon, attaching to this answer, probably. If it’s not already possible, of course.)
My votes are over (not sure if I’ll be able to vote again tomorrow), so it is a must for me. +1 for this.
EDIT: I’ve just read the pinned post on the main page. I’ll try to make better use of my votes next time.
EDIT2: Here’s the discussion I talked about unlocking the vault/items with the fingerprint.
