Agreed. That would be very helpful, especially for players who are saving sidequests for later classes, so regularly have numerous quest icons on every map. Have a special icon to identify quests that (while they may be trivial) should be done now if you're going to do them at all.

Since noticing that the Lightning Strikes event currently going on isn't even getting advertised on the launcher (at least as of the day before yesterday) I keep wondering if other events have gone by that I never even knew were happening. Currently, the only way to take part in special events is to look them up online and find out where to start them, which of course we can only do if we're aware of them in the first place. An in-game marker would be much better.
