Right Handed UI (User Interface)

As a right handed, I find it a little irritating that whenever I drag a plant, from the default left side of the screen, my right hand blocks my view of the battle. I know it only take a few moment, but that few moments takes the enjoyment of seeing more of everything that is happening . It is like travelling on a picturesque landscape and my window view is constantly/intermittently being blocked by a moving curtain.

Suggestion: enable an option to either put the plant box in the right or bottom of the screen.
