I have seen in the Piskel Editor that the button for changing the location of our image, we are currently working on, doesn’t show up nicely and it is almost inaccessible
What I generally do to have access to the button is by holding Shift + Spacebar + Rolling Mouse Wheel Down.
It actually zooms out the image but it also slides the top bar to the left and the button becomes accessible.
I would like to have the top bar mended in the next update.
