Is your feature request related to a problem? Please describe.
Having all quests always visible makes it a hassle to locate and track specific quests. especially at max level where you have quests for many different zones/campaigns

Describe the solution you'd like
The ability to collapse/expand the quest log by clicking on the title of the zone/subject. for example. clicking on the word "Nazjatar" would hide(collapse) all of the nazjatar quests underneath the word, perhaps with Nazjatar (4) still appearing to show you have 4 quests to do. and then clicking on the word "Nazjatar" again would show(expand) all the quests that were hidden.

Thanks for your suggestion.

This seems there are new things in my todo list.

Love this idea. Like the old Monkey Quest addon. To be able to focus only on the zone you're in
