[Feature]: Icon Background Toggle

[kattcrazy]

Requirements

• I have updated Mushroom to the latest available version
• I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

I find the new removal of backgrounds from icons on some template cards makes my dashboards look less organised and uneven, and I have no way to add/remove it without using card_mod (while possible, this seems unfortunate to have to do for a previously existing feature).

E.g, the card to the right of "Foodtime" has a entity tap_action set, while the others don't.

Describe the solution you'd like

I would like a toggle or an option to turn the icon backgrounds on or off available on all mushroom cards (or at least the template ones).

OFF - AUTO - ON

perhaps? Auto would let the background set itself depending on the action, as it does currently.

Describe alternatives you've considered

In addition, a jinja template field in the template cards would enhance the icon background, so you could say (for example). when entity > 1, show the icon background

Additional context

Thanks for making Mushroom card :)

I stumbled upon the same problem but while you seem to be successful with card_mod, unfortunately I am not. For example the following card-mod does nothing for me when using a template card. On other mushroom cards it does seem to work though.

card_mod:
  style:
    mushroom-shape-icon$: |
      .shape {
        --shape-color: orange !important;
      }
