Thanks for this card.

It would be nice to be able to set the amount of time that the card is unlocked.

Also, in the enter password popup, if someone presses the cancel button it would be nice if it simply canceled rather than pull up a new popup that says Invalid Password.

would be great to lock a card automatically based on another entity state, example if a person is not home, they can't control the lights if somebody is at home

Came across this card after having written my own version, but didn't have a condition; great idea which I added. https://github.com/custom-cards/restriction-card#condition-options. Thanks!
