This small addon will change the usergroup text to show the usergroup colors in a couple of places in the ACP.
It shows in the following locations.
1) Usergroup list page.
2) Usergroup edit page.
3) Usergroup permission page.
4) Usergroup permission edit page.
Below is an example of what the addon does. Note that this does not add colors, it uses the colors you have added for your usergroups.
