keep lock settings permanent

[poggenpower]

"lock settings" is very useful if your settings e.g. global variables contain sensitive data.

Unfortunately it is a one off action, once you have unlocked the settings you need to make sure to lock it again manually, which requires certain discipline and may missed accidentally.

Request:
Make "lock settings" permanent.
Or the other way round. Lock settings again, if app goes into background or a lock button is pressed. Preserve existing password.

Security considerations:
Even if the password is cached in the app while settings are unlocked a compromise is far more unlikely as leaving the app totally unlocked accidentally.
As the password is only cached if settings are unlocked, this exposure is very rare.

Thanks for the suggestion. That makes sense to me. The locking feature was built in a very simple way, but I think it's time to extend and improve it a bit.

I will change it so that the "Unlock" button will no longer remove the lock, but just temporarily unlock it. The app will remain unlocked while in active use and will then auto-lock after 10 minutes in the background, or if the "Lock" button is clicked. In the Settings, the lock password can be changed or the lock removed entirely.

I will include this change in the next release.
