Hi, I would have selected "code quality" "design quality" "feature availablility" and some more points - because this thing is simply awesome.
If you looked at other admin templates (back in the days there was adminLTE which is bootstrap / jquery based) those were already great solutions, somehow customizable but the level of _integration_ of primer is supreme and I would almost say unseen.
It currently already features angular 4.3, you just fire up yarn or npm (no bower or extra silly tools like that) and go for ng serve - it works. it runs. it just reloads no matter which kinda file you touch - translation files (en/fr.json), sass varialbe files, ts files, template files - you name it.
Also, the way the code is organized is brilliant, sections for all the modules that reside grouped in submenus, a folder for every submodule etc.
Everybody knowing his way around with angular2 / 4 and a basic understanding of npm/yarn, webpack and file watchers will be sooo happy with this package I'd say.
The only thing I had to do actually is to add an import for the @swimlane/ngx-datable sort icons in app.scss as they did not display first:
@import '~@swimlane/ngx-datatable/release/assets/icons.css';
After that the sort icons appeared immediately and I can now go on and build something with it
