Hello! As topic is started, I suggest this to a roadmap http://git.savannah.gnu.org/cgit/guix.git/tree/ROADMAP <http://git.savannah.gnu.org/cgit/guix.git/tree/ROADMAP> :

znavko`s  roadmap suggestions:
- total guix architecture guide (not only descriptions of cases ‘environment’, ‘system’, ‘package’ and its options) with pictures,
- interface for searching for substitute servers or a list of available servers
- searching interface for packages substitution (server url, system type, package version), how you can find server where package you need is compiled
- feature for getting source config.scm used in `guix system configure` (for beginners when deleted or modified to unworkable)
- count estimative compilation time for every package in different system configurations and display it  for user system configuration when run `guix package -u` or `guix package -i name`
- promotional video with infographics why to choose Guix and GuixSD

Also this:
- wiki with operating system configurations (starting from a subject, but not from existing options): system packages, services configurations with examples and full list of variables even where to paste it,
- Guile and Scheme for Beginners book.
