I'm totally in love with this new mouse! (M720). I just noticed a notification for when caps lock or num lock is being turned off/on. I'm glad but to me what is really needed is a small icon in the tray (not a large screen notification) that is on all the time telling you whether those keys are activated at the moment vs that you just turned them off/on (then the notification disappears). Being that some keyboards surprisingly don't have an indicator light on the key itself, what is really needed is something that will do exactly what the small light on the key would do, where a quick glance tells you -- you don't have to hit a key to find out.
