Cybernetec, I think it is better to replace:
Code:
Usergroups excluded from legend (comma separated ID list)
with
Code:
Usergroups shown in legend (comma separated ID list)
And set it default for 2,3,4,5,6,7,8
This will avoid misunderstanding.
As for example on my forum I have a big list of technical groups + I have hidden groups. When I installed this one today I need to add about 10 groups to exclude list. And for some period of time users were able to see my hidden groups.

At the current moment every time I add a new user group I have to remember to exclude it! Not the best variant.
