Be able to customize sharepoint group page URL.
We initially evaluated SharePoint before purchasing Office 365 and created a group called Office365Evaluation. Later we changed that group name to fit our company's name. However the name change was not reflected in the URL which looks like:
The Site Heirarchy only allows you to change the url of sub-sites and not the main group page. I recommend adding that as a feature so groups could be renamed without having to create a new group and copy everything into it (which is what a tech rep told me I would have to do).

I have this need! Especially with O365 groups sprawling, this is needed when someone creates a group that then needs to be renamed because that name is needed for another group (priorities shift).
