The ease to use tool is easy for any novice user with little or no training required! It's also very configurable allowing you great flexibility when working within your own business processes/procedures as well if collaborating wtih other vendors (or even outside partners).
Nothing really I dislike but perhaps some minor UI updates could be beneficial? Not sure why it isn't updated all that often - maybe they are too busy fixing bugs?! Maybe consider adding an "undo" option so we can go back through our changes before committing them permanently- this would help prevent us from making silly mistakes!! We have been able easily create templates using different fields which then allows others who donot know how these tools work effectively without getting frustrated by having new users come into their office asking questions about what has already worked previously etc..
