With the increasing popularity of mobile incarnations of PowerApps applications and the use of the SmartPhone screen layout, it would be REALLY nice if we could resize the controls e.g. make things like Radio Buttons or Toggles smaller to fit more comfortably on the smaller screen real estate. Trying to resize them at the moment just reduces visibility of the control. Perhaps constructing the images as vectors instead of bitmaps? Or offering different size option for the control if you're doing a phone app as opposed to a full screen app.
