Would like for the quest filter options to save our selected filters.I keep forgetting to turn on life skill quest every time I log into my life skill character 

I agree this is rather tedious to have to remember to check Life quests on every time you log into your character. It should remember those settings.

Another handy feature for the quests would be to check off which ones you want to appear in the quests list that hovers under your mini-map. When you have 20+ quests active you're not doing them all a the same time, it would be nice to pick which ones you want to see active.

One more little thing that's annoying, when in quests list they're separated into categories like life quest, story quest etc and you can collapse or expand those lists, which is nice. But when you close the quests list and open it again all the categories are collapsed again. It's not a big deal but it would be nice if the list remains how you left it.

I agree with all of these points. I keep forgetting to select these quests and I have no idea why it doesn't save, or at least have a save option.
