Categories are difficult to configure

[lainets]

Categories cannot be configured easily. E.g. setting accept_unofficial_submits is difficult. append_content in conf.py can be used but it is a bit cumbersome.

append_content example:
File conf.py:

append_content = [
    '_config_aplus/categories.yaml',
]

File _config_aplus/categories.yaml:

categories:
  submit:
    accept_unofficial_submits: True
    status: nototal
  feedback:
    accept_unofficial_submits: True
    confirm_the_level: True
