Maybe I didn't find the option, but it would be nice if, like main quests, the yellow side quest markers would pop up on the mini-map and above the NPC heads. My memory might fail me, but I remember that being a thing in the original Tera, which leads me to believe I might have overseen an option somewhere to enable it. It is tough having to talk to every single NPC just to see if they have side quests.
Otherwise, I think it would be a nice feature.
P.S. I can understand and speak German, so it's okay to answer in German. I just don't like writing in German. Life isn't long enough to learn German grammar properly
