It would be nice with an text-filed above the questlist, and if i write a word in there, al quests that dosn't have that word/string in its name, should hide.

Current workaround: sort alphabetical, scroll until you find it. (slow if you have no filters on)

optional:
if you write an integer in the field, also include quests with quest-ids that starts with that number,
so if i write 364, any quest whit 364 in its name (around zero) and all quest with id: 364, 3640-3649 and 36400-36499 are shown in the list.
