The ability to create issues from within our WordPress site (which we use for customer reporting).
It's also very easy in using this software if you're not experienced with it yet - I was able help my colleagues learn how quickly! Nothing too much at all really but maybe more explanations of what each button does or an easier way around certain functions that may be confusing would have been helpful because i'm new myself so there could always improve things as well :) Good product though which solved some problems by bringing them into one place rather than keeping multiple systems up-to date etc!
