I know this might seems frivolous but I have very active kids and nosy ones at that! Making a suggestion here because parents can't be everywhere at once. I like the control panels behind the door but is there any way you can install a simple cabinet lock with a key? :) Also when you look next to the control panel cabinet I see three things that should be inside the cabinet like the thermostat etc. behind lock and key lol Are you sure you don't want to borrow my 6 year old son for about an hour he can point out all your easy access issues you may want to re think before selling this to anyone with kids.
