We currently use django-compressor to compile and minify the static assets in horizon. There have been some concerns that the behavior of this module is too hard to understand, and django-webpack-loader has been proposed as a simpler alternative. We should see if it is possible to use that solution instead (including support for switching themes) and if it simplifies development and deployment as claimed.
