User dependent themes

Hi, I’m not happy with the handling of themes so far.
I have 4 different users using different themes.
A display user on my tablets to just show states, my wifes and my childrens users and my own one.
All of them have different right configured in CCH (i.e. kiosk mode for the displays).
When starting HA on my notebook, always the default theme (back-end-selected) is set.
When I login with my own user, I would like to choose a certain theme automatically.
But the only possibility is to set the theme with frontend.set_theme when startup.
Doing this, the theme for all users changes to this theme, which is not great for all my wall displays, logged in as user “display”. I have to change the rights with CCH for this user, relogin and set the theme, go back to the notebook and change the CCH settings again.
This is a pain.
My propose is, to advice a certain theme to a user which is always set when this user logs in.

I am not sure, but maybe you can handle that issue with an automation? If a user logs in the theme will be loaded with an automation. You can use this action to set it:

    action:
      service: frontend.set_theme

Nope. There is no way to tell which user is logged on in an automation.
