In a recent blog, your team indicated you could position a background image to your liking. Currently it appears on the very edge of the display (no gap). It would be nice to be able to specify an offsetX/offsetY setting, respecting backgroundImageAlignment to determine which sides of the image to apply the offset to, so that you could indent the image. The idea is that most people will use this to position a large-size icon somewhere in the window to make it super-obvious at a glance which shell is being displayed. Currently to get a gap you need to manually insert a gap around your image, and getting the transparency right isn't necessarily easy.
