This is another issue I was hoping HTC would address. I loved the way the indicator light on my S4 would use a particular color, depending on whether it was an SMS, an e-mail or a Facebook message. But beyond the color issue, the Galaxy line uses a nice, bright, constantly on indicator. With my M8, it's one color, very faint, and it only blinks every couple of seconds. It may sound silly, but I find it annoying having to stare at my phone for a couple of seconds, for it to indicate if I have a message waiting. Like I said, it's not a deal breaker item, but it's one of those usability factors you would hope companies would address in updated revisions.
