How it should work:

• Display the effect name in the header. Align it to the center between button group on left and help icon on right.
  
• Add an edit icon next to the name (use icon: edit_medium)
• Clicking on Edit icon opens up a pop-up in which the user can change the name. Button order based on the OS. Picture below shows just the functionality, not what it should look like. Use the style we already have.
  

• Validation should be similar as when creating an effect and naming it
  
• If the effect list/stack has not been saved, we show an asterisk at the end of the name
  
• Renaming, and saving right after creates a new instance of the effect.
