I love to use the back/next button from the browser. So far I could see, all "tabs" in MODX manager only use an empty location.hash. Hopefully the team will build the option in to switch to different hashes (thus enable back/next button on tabs). So the href="#" for the resource tab can be href="#resource" or for the elements tab to href="#elements".
Or for example in the Access Controls: href="#userGroups", href="#roles", href="#accessPolicies", href="#policyTemplates"
