I like how easy it was to customize what we needed, as well as being able update in real-time with our client's site changes without having to go back through each page one by one; also that there are many 3rd party plugins available out of box which helps you save time & money! Not much - its been good so far other than some minor issues here or there (which could be addressed). We were looking for something where both clients would have access easily but at times when they're not working together things can get confusing if their accounts aren't exactly synced up. This software has helped solve this issue very effectively while allowing us flexibility from different locations via VPNs/SSH connections etc.
