Is it possible to make the UI simpler?
Since you are using Drupal, I would also suggest considering how much you can save most users getting in to CiviCRM at all, and providing a lot of the UI via Views and Webforms. We have done this for chapter based organisation, and this has often involved using the Permissioned Relationships extension to provide the ACL.

The outcome is that the user can have a (menu) block with links to all the things they most commonly need to access and do so purely by visiting Views and Webforms
