Right now, the QSD is pretty simple. I think it would be a nice if instead of requiring the book item, you could open a gui that allowed you to select the task and show the progress on that task.

The selectable tasks would be a scrollable list that, when selected, populates a portion of the gui that shows each element in the task and the progress each thing has. This would be helpful for people working on teams, so everyone can see what the thing is doing and would make it much nicer to use.

You could also continue the compatibility with the book by making the first element in the selectable list be the quest you have selected in the first questbook found in your inventory.

(If you like this idea, I will submit a PR with this implemented)

Sounds like a good enhancement. How would the gui layout look like? Where does task progress show up in relation to the selection list? What other info will be seen from the menu? (Things like quest name, quest task name, quest description, quest task description)
