In many quests if you click on the quest box on the right hand side (after taking the quest) it will show a location you are suppose to go; but some of the quests have no such 'location' to travel but rather an objective. It would be very helpful if when you click on the quest it either shows the objective or redisplay the original description.

It would also be useful is quest points showed up on the cloth map so you can easily find them all (well the ones you've discovered). A 'black' star or similar might do the trick...
