- about-page:
  * The page, like the rest of the pages, must be finetuned for responsive
    layouts.
  * Either provide no image or upload your images!

- Do we need ALL the boilerplate of bootstrap css?

* Layout / CSS:
- Firefox Reader Mode does not display all of our pages in full.

- architecture-page:
  * The graph image does not really display well on small screens.

- branding / navigation:
  * Can we get a hover image for the navbar logo?

- Makefile:
  * conditionally without gmake extensions pick up values for BABEL and
    PYTHON. They can be python3, python2, python2.7, pybabel, pybabel-2.7
    etc.
  * Ideally don't require gmake to run make.

template.py:
  * it is currently broken with python2.7. Since I use python3.7 and
    2.7 is on its way out: person who cares enough for 2.7, step up
    to fix this in a portable way (in other words, do not break
    various corner cases for relative imports in the 3.x series!)
