Working with other users' dashboards has lost functionality - in particular, the ability to work with another user's dashboard as if it was your own (open records in workspace, return to the dashboard etc. ). This is no longer practical in BBGM.
Suggested improvements are:
Place the Manage Dashboards button next to the other Dashboard controls (Share, Copy, Remove, Reorder etc) - available for Admin users
Open the selected user's dashboard within the same Dashbaord page as is used for your own Dashboard
Preserve all functionality when using another user's dashboard
Switch back to your own Dashboard when done.
