Improvement: for crmUiWizard-driven workflows, scroll back to top between steps
Some "steps" in a wizard are fairly long and require scrolling to reach all the required fields. See the CiviMail wizard (civicrm/a/#/mailing) for example.
Differences in height between the steps can make clicking the buttons that control the workflow (back, forward, etc.) at the bottom of the wizard a jarring experience. Sometimes the next step is significantly shorter than the previous one, and the user is left looking at white space. Sometimes the next step is very similar to the previous step, and it is unclear that anything occurred after the user's click because the user's view hasn't changed.
In any case, a better user experience would be to move the user to the top of the wizard at each transition.
