New tile feature requests - generic features

[BBE-FR]

I think that tile card is becoming an amazing and versatile card.

Nevertheless, we are sometime blocked by the lack of features to implement those cards in our dashboard.
The latest addition of the toggle feature in 2025.3 is adding a feature for a huge number of entities, but there are still a lot missing...

Some example (non exhaustive list obviously)

• media player buttons
• colors slider for lights
• no feature for sensors (a bar or graph would be great!)
• no possibility to add info from another entity or control of another entity

Instead of trying to create a dedicated feature for each entity type, maybe it would be useful to create some generic feature that would be user controlled. For example:

• generic buttons (chose a number of button, and define for each: tap action, state, icon, color) with the same design as cover or vaccum buttons :
  
• generic toggle (chose which "togglable" entity to control)
  
• generic slider (set min, max and entity to display or control) similar as the light feature
  
  this one could be available for sensors to replace a custom:bar-card for example
• etc...

Like for the hold or double tap actions, theses "advanced" features could be "unlocked" through yaml, and once unlocked available in UI graphical interface.

Just discovered that https://github.com/Nerwyn/service-call-tile-feature now has graphical UI...

This is fully covering my personal need.

But I assume (and hope) that a minimal core implementation of a similar generic feature could be performed.
This would allow anybody to add simple feature to any tile...

I still have the feeling that we lack a "simple" way to create custom features.

We need an easy and simple way to create buttons or slider, for example by just defining an entity and the associated tap action of a button (like a nano tile card in term of complexity) without having to go full yaml or even CSS...
