Some project information has disappeared from the new Projects page compared to the legacy one. One important thing is that it doesn't automatically show anymore most project attributes. I suppose this is linked to the fact that the Projects page now shows project groups rather than projects. Some project attributes are still visible though, like the due date, which seems to show the latest due date of all due dates in the project group.
Custom attributes, however, are only visible after expanding the project group. Reloading the Projects page (including auto refresh) collapses them again. This is all not very convenient. Part of the easy, comprehensive overview has been lost.

Custom project attributes are often the same in all projects of a project group after a project has been created. In such a case, wouldn't it be possible to show such project attributes also on the project group level, so they're also visible on the Projects page with the project groups collapsed?
In a case where project attributes are not the same anymore for all projects in a project group, you could simply not display them in the collapsed view and instead show a message "expand to view" or something similar. At least then you know the attribute has a value and that the values are not the same for all projects in the project group.

In any case, functionality has been lost in the new UI: having one compact and still complete overview of project information that a project manager wants to see.

I'm open to other ways of solving this. E.g. I could also imagine introducing custom attributes on the project group level (this is not possible now), which could be displayed on the Projects page without expanding the project groups.
