Saves searching for what is needed. Would be better if more guidelines were included such as component selection ### 5/5 — Great app *2017-07-23* App is very user friendly, clear and easy to navigate. Guidelines and information are all relevant and up to date with current publications. The main icon design could be a little better designed (quite sinister looking!).
