It's very clear what you are looking for when searching through your list of contacts, this makes it easier if any employees leave or have new contact information added (which happens frequently).
You can't search multiple groups at once which sometimes means having duplicate names that need removed from one group but not another! If I could just add more filters/search criteria would be great - right now we're stuck with only being able filter out people who don;t work there anymore since their old card was destroyed without leaving us much choice other then manually adding them back into each grouping category every time they change jobs etc :( This has been quite helpful so far though! We used something similar before switching over completely however didn'r like how cluttered everything looked compared against ours previous system where all info went straight onto 1 sheet per month instead off several different lists within folders :).
