In Frog Finder you have generally two options: shoot or guess. I know that it is caused by my own stupidity, but today I guessed two times when I wanted to shoot and I shot one time when I wanted to guess. Very annoying ;)

So what I am suggesting is to have a different marker for the field when guessing. Maybe a flag, similar to the well known Minesweeper. So I would notice that I did click the wrong link before hitting the submit button.
