Two subtle tips for those who like work with the workplane grid visible. If you do use it often you probably already know them?
First when you rotate the grid you'll find that the rectangle sketching option will be constrained to align with the grid. Also it will be easier to sketch and align to the angle of the grid.
Second if you are zoomed in on the grid, how do you select it? Zoom out so you can select the edge? Well you don't have to. Two ways:
One: click Tools menu > Select Work Plane Grid
Two: Click Workplane button > Click OK (selects the grid as a result)
