Group/project creation screen

What is your feature request?

1. Not all locations should be required. Most groups will not get mirrored storage for example. Projects might not require Tier 1 storage.
2. Empty fields are shown "pre-filled" with a default folder name, but judging by the error message they are really empty. The message also does not catch the fact that the field is empty and shows a formatting warning.
   
3. If the folder naming is this strictly enforced, these fields do not need to be editable at all.
