The feature

I am using immich kiosk as a card in home assistant. I can click on top of it to go to full screen to present photos, and then, when I want to go back to the HA dashboard, I can do the same again. It may seem like not much, but ideally I'd like to be able to do this with a single click. It would really enhance this workflow.

An elegant solution to that which I would suggest is configurable screen buttons/areas. For example, clicking on the right part of the screen would switch to the next photo (like now), but clicking on the left could be overridden to toggle full screen or other possible actions. Or additional area could be added, say the center or some corner.
Any form of configurable actions per screen area that allows assigning fullscreen toggle would do the trick.
I recall that the the moon+ book reader has a lot of configurability around that - different area layouts with assignable actions.
