Setup default dashboard for users

[eager sorrel]

Hi all! New to HA, not new to managing a server. I'm using a docker approach with the ghcr.io registry, and I'm on the stable image.
The dashboard feature doesn't work how I imagine it would work. The rest of my family is not tech savvy, and cannot setup their own dashboard. I want to create a dashboard (that I can edit as-we-go) that is used by every user of my HA instance by default. It's a gigantic pain having to login for them, and then click a few buttons, on each of their devices (if they'd even let me :p). How do I achieve this? Or is it a HA limitation that an administrator cannot administer dashboards? Thanks in advance.

TLDR: How to set a default dashboard for new users on all their devices?

Take control of the overview dashboard and customize it as you wish. That is then the default dashboard for everybody.

HA is hardcoded that a client with no saved preferred dashboard goes to /overview. But what that dashboard has on it is up to you.

I see - let's see if I can figure out how to modify Overview as opposed to creating my own from scratch. Thanks a lot for the insight!
