> Starting the installer right now leaves the user with about 3 seconds of staring at an empty window before the content shows up.
> I've done a few tests on this matter and it seems majority of those 3 seconds is spent on angular bootstrap - mainly loading the required files and registering controllers. Replacing the index with simple static HTML causes the page to render almost instantaneously. 
> We should consider some way of showing the GUI before the user falls asleep (before angular fully loads the entire app).
