[Question] Should traits be disabled / hidden when no component is selected?

The style manager seems to have a nice solution for when no component is selected by showing a "Select an element before using Style Manager" message, but the trait manager does not. This is pretty easily seen in the newsletter demo:

• Select any component
  • Toggling between the style and trait panel works as expected
• Delete the selected component
  • The style panel options are hidden and replaced with a friendly message 👍
  • The trait panel is still populated with the traits from the (now deleted) component 😕

I'd be happy to work on a pull request to make this better, but I'm not sure what the desired behavior is... Should there be a message in the traits panel similar to the one in the styles panel?
