I'm not sure if this is a bug but it's annoying to me. The board keeps moving to the right whenever I click on any element on board, then move to the left when I click the space outside of the board. No matter I zoomed in or out, or manually moved the board to the right so I can see what I need to work on, it will always move back to the center I think. I kind understand why it needs keep moving so the board can stay in the center but it is also very disturbing to try to "catch" the elements I'm working on everytime I click on it and release it. The board movement is just a little too much for this crowd web space. Please review and improve it. Thank you.
