Add a label in fav action

[fcoveram]

Is your feature request related to a problem? Please describe. The heart icon for adding a theme to my favorites looks floating in space without other visual traits that attach it to the page.

Describe the solution you'd like Add a label to the button's left side:

• For the not added state: "Add to favorites"
• For the added state: "Added". in this case, the label could disappear after 2 secs.

Describe alternatives you've considered If this solution takes big effort, we could just added a label for the first state; before clicking on the heart.

Should the text just be floating next to it, or do you want an outline button like on patterns?

The outline version like in Patterns looks good 👍
