It's just another UI inefficiency. More clicks to achieve the same results. Majority of players go to Bounties first, quests second, the arrangement we see just shows developers don't play the game or not the same way like their player base. We all know the additional cursor movements and clicks it takes us to reach destinations, start an activity, change loadouts, look up data, descriptions, perks etc etc etc.. In terms of LEAN thinking this (the UI) is the Muda of playing Destiny.
