Amongst us players(especially new light players) I would believe there are plenty more suffering from overflowing quest chains that deny the gathering of multiple bounties.
Having them separated would be insanely awesome as a start but if not, increasing the maximum quests by alot would also be a fix.
Having that said, this would be a duplicate request for sure but I would like to add something else.
There are multiple quests from vanguard, gambit, crucible, etc... that require A LOT of grinding and take up space in your quest list. They're all in random order as well so being able to sort them into gambit quests, crucible quests, vanguard quests, world quests, etc... would be sweet as well.
