Hard to distinguish visually tasks
When you have a list of buckets and a list of tasks in each bucket, if you have some tasks assigned to someone mixed with some tasks that are unassigned, it is pretty hard to visually see which tasks are assigned or not, and seperate visually the tasks.
It is hard to see if the title of the task belongs to the above or below line.
A visual seperator would make life so much easier. Or add some kind of themes for the user to select.
