In Google Analytics, I would have to:

* click on "Websites" (top left of http://gget.it/5e8tyn6g/2.jpg)

* choose the right website in the list (http://gget.it/8jptjvso/3.jpg)

* wait that the page reloads

This, ten times in a row, which is annoying (once per website I manage).

Conclusion: more time spent on clicking twenty times on UI elements than actually looking at the charts.

I like to go super fast, now I open http://mywebsite.com/tinyanalytics/, and I have an immediate overview of all the websites in 10 seconds.
