Zakira's 2nd quest is the last of the Main quests, for now. Although I can't figure out why you keep seeing 'The Gauntlet' quest since it should disappear from the log after the second H scene with the blacksmith, so I'll take a look into that.
Other objectives, like recruiting the girls, don't appear in the log, though I could add them in a future update if it becomes difficult to keep track of all of them.
