Not liking it either. I always set up my own views, since I use dates received, delivered, and need info columns only. Eliminating unused ones is clunky. 

In order to set up or later change the special view, you have to go back to the default view for that return type, click the menu to filter it, then the set up window pops up and you can go to the special view to add or remove columns. 

Too many more clicks, it will take getting used to. 

If you change column widths by dragging, use F5 to reset and save the new widths. I think that is working.
