Sorry, it's me. I was confused by the change of look of the search result.
The result of search now looks like in the virtual GPS.
In the virtual GPS you could find the group function well visible (i use a lot 'by department')
In the search result, you have to click on column 'Department' to sort it (and group it)
The only remaining suggestion is then a convergence in interface. (for search and for Virtual GPS). Many thanks for your quick response and for your site which become even my first landing point for caches management. (yes, for creation/update of cache still go into geocaching.com :-)
