I really love the project overview (and brief, and nested portfolios!).
I would LOVE to see more options for App rules for Slack to make this feature useful for us, for example: Milestones and status updates to Slack Channels (I don’t want every task update in Slack, as this results in redundancy and clutter for us - but right now tasks are the only option).
I was sad to see that the workload feature did not work in nested portfolios - hope to see this one day!
