If you have to check many kpis from many clients/sources, you will love this little tool. Press ctrl shift i and you will have all on them in one beautiful view with really fresh datas (you can automatically refresh every minute if you want). You can also set notifications if those kpis reach certain goals (bad or good)
Really a great time saver.

Hope the mobile app will be soon available and maybe a little more customisation in the way datas are displayed
