;;; The pattern from the re-com demo (https://github.com/Day8/re-com) is to have
;;; one source file/namespace per view. Each namespace contains a function 'panel'
;;; whose output is an enlive-style specification of the view to be redered.
;;; I propose to follow this pattern. This file will provide the issues view.

;;; See https://github.com/simon-brooke/youyesyet/blob/master/doc/specification/userspec.md#issues-view

;;; Simple list of the issues of the day.
