I was almost positive this had been requested somewhere but I can't find the issue for it, so I'm making one so that I can reference it in the commit message.

This is technically resolved but there are two remaining issues.

• Better handling/placement of the button for adding a new task (it's off the page)
• Better handling of non-existed advancements. Resetting to null may be more desirable than simply crashing completely. Alternately, storing the text name but not trying to find the advancement itself.
