A quick sketch to show what I do, and what I think
@raisins is referring to. First sketch is the larger picture of how I try to position my platform on the tree with respect to my anticipated target. Again, I'm a right handed archer, things will work differently for left handers.

With that in mind I then typically orient myself something like the below sketch in the tree for my sit. By shifting myself, and my tether point, slightly to my right of the platform I can see virtually all of the area I'm hunting by just a swivel of my head back and forth. The stuff behind me is direct downwind so I'm not as worried about watching that. I'm typically knees to the tree so I'm as small a profile as I can manage, especially on single trunk trees. From this position I can shoot without needing to move from the 4 to 7 o'clock directions or I can rotate slowly left to get better footing and shoot more traditionally from the platform for the 6 to 11 o'clock positions. Putting the stick on the tree where I do allows me to make one step with my left foot to the stick for shots between 11 and 1 o'clock and by stepping both feet onto the stick I can now shoot from 1 back to 4 o'clock. This set up gives me full range of shooting and allows me to visually see anything approaching that isn't directly down wind without too much movement.
