[Plugin: BP Group Hierarchy] Fixed top level groups

hi david
Your plugin is the the best so far in group hierarchy and many thanks for developing it.
But it would be better if you add this feature.

I would explain my case, My site is a sports website which need group categorization. something like this.

groups —> football —> football in state, football in town
basketball
baseball

In the above the first level of group categories( football, basketball, baseball) needs to be fixed.

When a user creates a groups it should be mandatory that he selects a main catogorization ( football,… ).

and the page football should not be displayed in groups list.because its actually not a group and just a category. (www.site.com/groups).
when we seek the url http://www.site.com/groupscategory/football it should display all the groups categorized under football.

I know that this feature conflicts a lot with your existing plugin.
but i have searched the entire web their is no plugin which matches this requirement which is mostly asked by many buddypress developers. you have developed a fabulous plugin i hope if you develop another plugin which categories the groups and display it that would be very effective and useful for many buddypress users like us.hope you do it.

with regards
Ezhil
