EDIT: cancel this first bit!!! in case anyone else is looking at this thread and wondering about setting look distance more precisely: you can bump it up and down one number at a time by hitting the up and down arrow keys while your left click is held down on the slider!!! i'm not sure if this has already been requested, but i was playing around with it today and realized it would be really helpful if we could directly input numbers for the "look distance" rather than just fiddling with the slider! you can get really cool effects by selecting certain pieces and having them all have the same look distance, but it can be difficult to get the numbers exact, especially at smaller numbers, when you're trying to just bump the number 1 value up or down on the slider by barely moving your mouse. (along these lines, being able to grab multiple different pieces while holding down shift and apply look at cursor settings as a batch would be incredible, but i have no idea if that might be super complicated to implement.)
also, i'm pretty sure this has been requested before, but just throwing a +1 onto the pile: being able to scoot pieces around with the arrow keys would be great!
