It is too easy to accidentaly hit the 'Back' button by mistake when a wizard is completed

This is another element of this report:

Specifically this:

Even worse, and in my case, you may accidently press back instead of done when you have completed your bug report, as the two are directly beside each other with little space in between. To resolve this, I strongly recommend either saving it as a draft when back is pressed, or adding a confirmation prompt that warns users of their impending doom. In addition to a confirmation prompt, I recommend moving the back button to the left side of the frame, as that is the standard in UX and will provide necessary spacing.
Back Buttons

I’ve done this myself!

It certainly makes sense to me for the Back button to be on the left side of the container, which is pretty standard across many applications. Also would make this particular user slip much less likely!
