The Artiq Dashboard Explorer shows the docstrings (or class name) for each of the object that extends EnvExperiment under the repository folder. How can I hide certain experiments from the Explorer window? I'd like to suggest a feature where a special character (or combination of characters) in the class docstring is used to let Artiq know if a class should be hidden. For example, if the docstring starts with a tilde such as """~ hidden experiment""" would not show up in the Explorer.
