but these mode don't have anything to do with target priority.

I want an option that allows you to select targets closest to furthest away.

Right now it only prioritizes from left to right or right to left not taking distance into account. meaning if you are targeting from left to right, it will target the left most mob first even if it's the furthest mob away.

Generally when you appempt to target something it's most likely closer to you than the at the edge of your target range.
