The old UI had arrows to move through records on a form. The new UI has none, and no keyboard shortcuts. this is a shocking omission!

Yes, I know you can open the side view on a form and jump through records that way, but (a) that takes up screen space (and on some forms crashed columns into one column); (b) takes longer/a bit more thought than an arrow or keyboard shortcut; and MOST OF ALL (c) that side view isn't even available on results from Advanced Find!

The loss of arrows / shortcuts to move through records is a HUGE error / omission in a productivity tool like Dynamics. Productivity is slower now for my company because of this loss of functionality.
