This really isn't necessary. It offers absolutely no benefit whatsoever to reduce the viewing space to a circle. Infact, it would be worse than the viewing angle you would have in real life. Displaying a circle would indicate you are looking through a telescope. Single lens. When you look through binoculars, each eye is magnified and your brain merges the two together, so you maintain depth of field, and a larger viewing angle. Its just not needed in the game. It offers no benefit, and not does not offer any advantage.

this is the same person to added the 'dual wielding' ticket. *facepalm
Also to correctly navigate using a compass you need to be able to rotate it upon the map.

This also happens in the Hunter.
A nice added feature for this would be able to shift + enter to add a line break.
Would love to see this fixed! Be great to equip backpacks from a crate.
