Range Indicator Request

I think it would be really helpful if we had a range indicator for the second cast of abilities like Zed's W or Lee Sin's Q to let us know whether or not we are within range to reactive it. I still occasionally have trouble with being able to tell whether or not I'm just outside the edge of my range and how sometimes I'll have to burn flash just to get back into range when I thought I was already close enough. Does this sound like a good idea to anyone? I'm not the only one that has this problem, am I?
