A quick set of mods to the basic Workload plugin, which include

• localized into english (config/locales/en.yml)
• layout modifications
• de-logo-fied (not that we don't like the logos, but we like our pages to look like other Redmine pages)
• default to no users selected when you first land on the page (to reduce load times)

• Look at implementing Redmine Group selector to view workload by Department/Group
