Modernizing Horizon using Angular is really great. I would suggest a couple
of minor things to consider.

First, font-awesome is excellent and free font, but there are two problems:
it has lots of icons that are not used, it also miss some other icons worth
to have. I would suggest Fontello, it is tool for picking glyphs from all
the free fonts round there and building custom fonts

Grunt is being forced out by Gulp that is times faster while having the
same level of plugins and tools and is easier to use

> TL;DR: piece by piece we will replace Django views in Horizon with angular
> views, and we're going to start with Identity
> First up, I'd like to ask the UX folk who raised their hands in that

> At the same time, I'm looking at updating the AngularJS recommendations in

> should also be revisited, if we're to scale up to the full angular
> front-end envisaged. I'd appreciate if those interested in this aspect in
> particular could contact me so we can sort this out as a team!

> broader discussion about the structure of the angular code in the Horizon
> application as mentioned above. Should it be a new blueprint/spec?

> Also, phantomjs so we don't have to fire up a browser for exercising (what
