Ok the pseudo quest reward stacking is not pseudo but an actual one.

Finally, no longer necessary to window how in between the menus, just do all the quests of that type at once and than just collect.
No more " go to gifts, give a gifts, hop to quests, complete, go to gifts, give 3, go to quests, complete" over and over again. Quality of life update that is much appreciated.
Now we need the "Collect all" button for the quests and life will be good
