Feature request: Accounts list columns

[Helve1ios]

Currently the Accounts list is missing common account details that are only visible when editing each account separately. Therefore I suggest to add the following additional columns to the Accounts list (maybe instead of the column "Created At"):

• Role (e.g. "User", "Administrator", "Custom")
• Usage / Quota (e.g. "2.5 GB / 10 GB")

Done in my webui here : https://github.com/LinkPhoenix/webui & LinkPhoenix@3dda6d1

Maybe the Stalwart's owner will be add this too.
