Can you please increase the hit boxes on the navigator expander buttons. So often especially when selecting a plane for a new sketch I try to expand something like the Origin and end up selecting whatever plane hit test to just clicking on the canvas. Also I generally have a lot of trouble expanding and collapsing items, having to attempt two or three times sometimes. I will get the mouse over and get feedback but clicking is enough to move it out of the bounds of the image. Who the heck actually tries to click on items in the drawing area that are behind the object browser anyway?? I think this can be done easily by making the image bigger and padding it with transparent pixels without any visual changes.
