The tabs are a really good idea but… :
For modifying fields, it’s good enough that way :
For modifying Access Rights and Identifiers, it’s not the best… Adding things should be in multi-tasking view and not a window above another window :
For instance, if I want to add another identifier, the window is above the main one. Therefore, the new one hides what is behind. I cannot see what I already have :
If it was on the side, I could see better.
If you look at the existing Dashboard for the Access Rights, it’s easier è On the left side, what you can add. On the right side, what we already have :
I believe piling windows is less readable than stacking them next to each other.
In overall, there are a mix of really small things that are not there yet or not existing and this makes this preview really quick to explore.
