This needs to be considered for the very next update. ASP should follow Procreate and introduce a background grid for ASP. This simply makes it easier to “see” the document placed on the board. So when you change the orientation or the angle the background grid makes it easier to see the location of the document. The “black” background is not only too plain and boring…it doesn’t tell you the orientation of the document and its scale. The background grid, like Procreate has, would fix this.
