I was testing out dataflow endorsements and found these issues:
Unfortunately dataflows only show up when you open the workspace folder in Desktop, however they should show up at the highest leve...

Solution SageEndorsement is set on the dataflow, not the Workspace. You can have dataflows with mixed endorsement in the Workspace.
A great use case for this is several staging or enrichment dataflows, combined in a consumption dataflow for your users...you don't want to have users wonder which "Sales" dataflow to use--they just look for which one is endorsed.
How I manage staging/enrichment/consumption dataflows now is in seperate Workspaces, using unnecessary Linked Entities which is cumbersome to maintain.
I'm guessing endorsement is only supported for Power BI dataflows and not Power Platform dataflows.
