Theme Customization

In "custom theme", whenever the board or pieces are changed, the background also changes automatically. It means that in order to experiment with different boards/pieces, I have to make the change I want, then scroll through backgrounds and pick my initial choice, then go back to home page to see the outcome, and come back to themes setting to repeat the process with another board/piece set. It is absolutely exhausting.

If you could please:

1. Stop automatic change of background.
2. Implement some kind of preview, to see all elements together without visiting an actual game.

I'm not seeing that issue. 

Are you in Custom at the beginning? 

It is for these reasons that I found one set I like and haven't changed it for months

Sorry, I don't understand your question.
