I want to change the background but when I do it is in the front blocking everything. How do I get it to the back without x-ing out everything and starting from scratch? Same question for other clothing items. Sometimes I just want to change 1 or 2 items but now the are not where they suppose to be. Any help would be appreciated :)

You can click and drag anything you adjust the layer it's on.

Here's a gif that demonstrates it (somewhat; it's not supposed to highlight when you do it, that glitch has been fixed)

Thank you :)
