The best part of this software so far has been its ability to create multiple views that are customizable, which allows me as an estimater/manager at my firm have different options depending upon what we're working towards with our clients' projects! There's nothing I dislike yet about it but if there was something then maybe some sort customization could be added in order make things easier (i'm sure they've thought through all aspects though). We use E36 mostly just because most other applications aren't really user friendly or easy enough when you need specific information quickly while estimating new jobsites etc..
