It would be nice if we could have some checkboxes in the compendium...for example:

"Only Show quests in this zone"
"Only show quests not yet completed on (Pick one): No Preference, Casual, Normal, Hard, Elite, Epic"
"Only show quests in level range (Enter two numbers (Defaults = 1 to 20))"

Also, pretty please, can we have a "Reload/Refresh" button for those times the compendium comes up blank?
