(2) (Yes, please.)

It would be great if the target circle had a minimum size so that it's still visible under critter-sized targets. Even better would be to have an option to set the minimum size, like

Minimum target circle radius:
Small (current implementation)
Medium (3y)
Large (5y)


though even a hardcoded minimum of, say, 3 yalms would be more usable than what we have now.
