The ease of use in creating our own templates which can be shared with other members within my organization as well those outside it! I have not found anything at this time but if there was something would surely let you know about them right away because we are looking into implementing some new features soon so i cant think what they could possibly do better now since everything works great!! We were able solve many issues related specifically around electronic signature capture from mobile devices or tablets using their API's when working remotely without having an internet connection available-this allowed us seamless access even while traveling via plane etc..
