Set threshold without target
I'd like to limit my caffeine intake, so I've set a Maximum Threshold. However, unless I also set a target that is non-zero, cronometer will not mark the caffeine amount as read if I go over the threshold. Alas, setting a target as well is counter productive, because now I get either a yellow color (if the target is set close to the threshold) or a green with 1000% (if the target is, say, 1mg).
Is this a bug or is it by design that target and threshold do not work independently?
