As a group product manager, I need to be able to curate visual roadmap and strategy elements from each of my teams to create an executive summary for my stakeholders.
This quickly gets out of date if I have to copy and paste or screenshot from their Miro boards into mine.
Having this capability to display frames from other boards in another board would help with keeping a single source of truth and address the document sprawl issues that arise with a large org using Miro.
It would also allow you to create a project board that curates from other boards - today I solve that by having my teams keep a shell confluence page with Jira epic links and Miro links and a light project description so we can link all the things together later in a structured way when we need to go back and remember what we did and why.
