I am so amused at the “HiLight” feature (lighting up colored LEDs for notifications so you can see them “at a glance” without looking at the screen). This is a feature that was on the Android phones of old (including the original G1) and I loved it, but it got phased out in favor of “always on displays”… which apparently now we want less of! It’s funny how trends like this are a circle sometimes.
The problem with this kind of feature is that it falls apart if you're the type who leaves things unread or gets them all the time. Then, it is little more than a beacon to say "phone still exists"...
