I'm an alta-holic and I have, at present, three additional characters I play with outside of my main character.

These characters are one-job wonders and will never complete 90% of the content in the game. They exist as a place for me to retreat away from my main character and the "must complete all the things" stance I have with her.

I would like the ability to hide all non main scenario quests. Put this as an option under Character Configuration, UI settings, General - "Toggle off optional quest markers." (That way, the odds of a new sprout finding by accident are low.) By keeping this as a toggle, we can de-clutter any quest markers when we're not actively looking to do quests, but turn it back on when it's time to find some NPCs.
