Thank you for your feedback, @dr_michaelmarks! The features you mention are definitely all important, and we're aiming to implement them. We've spent part of this week planning our next couple of releases, which will include more project management functionality. As we roll that out, I think we'll have more functionality around (3) and (4). We're planning to continue releasing new versions regularly, and as we do so, I think we'll be striving to both implement functionality that already exists in Aggregate (such as user deletion) and roll out new functionality (such as project management).
@Felix_Mutua, as part of that new project management functionality, there will be improvements to how app users are organized. Those improvements should help reduce the number of app users you see on a single page. In addition, we may also hide revoked app users in the list by default. Would that be useful?
As part of the next release, we're also planning to add the app user name to the CSV.
