I deliberately avoided feedback in the app loader
I agree with a separating feedback from the installing function, but maybe having a link to the github filtered result.
By "feedback" i was referring more to personal opinions or functional analysis, focused more in end-users than in issues/technical feedback as bugs or feature demands focused on developers.
In fact i just realized that my example (reviews page of firefox addon) lacks of a version number field (btw google play reviews lacks of it too), and imo it is must to have info.
Through fields and filters I am sure that Github can manage this review info :)
