Suggestion: being able to f3+c no matter what if crosshair is in the right pos

[krankyy]

So for example when you try to boat eye, and you do that incorrectly, it will show the red boat and you wont be able to f3+c untill you turn off boat eye and move around/move crosshair(which will make measurement incorrect). So my suggestion is to be able to f3+c even if boat eye is red and add like a text "you tried to boat eye but it was incorrect" or something like that.
I get it that not seeing red boat is my problem but sometimes you try to do that fast and dont look if your boat is red or not, you just throw eye and only after that you realise it
Also probably thats doesnt make sense since in 99% of the times you will need to throw second eye anyways if this will be implemented but whatever, my goal is to suggest.
