I would like this as well, but with this tweak: give me a way to set a time limit that I'm comfortable with, both using the website and especially with the iOS app. Other security-conscious apps (e.g., 1Password) have very nice controls that determine when the app closes itself, and even how tightly in the case of 1P (full password vs. 4-digit code).
I'd even be OK with this as a ProtonMail premium feature, as long as it's a feature.
