Something that I reacted to after I bought the Rainbow Orb was that the button to preview had been replaced by the button "Update".
I think it would be easier for users if there could be a "Preview" button available even when you already bought the orb.
That way, you would avoid having to update the orb everytime when your only intention is to test different colors.
This is how it looks when you bought the Rainbow Orb.It would look something like this, if the button would be added.Feel free to leave feedback and opinions about this suggestion.
