Functions to change the appearance of Zanata. This could include things such as:
Logo image url
These would be applied in a context, or component, eg. Sidebar colour, background colour or image, text colour etc
We're seeking to incorporate this into our infrastructure where most of our tools are themed to our project, but Zanata currently seems to lack theming options for the web UI. Having at least some build in customization options for CSS and logos would be great for tying it into everything else our developers and translators work with.
