I apologize for the length of this PR...
There is no version bump yet, as I want to do the release later, when the GUI itself is ready.

Unrelated but since I saw some ArrayLike instances in there and it relates to #407, I have found the fix for their expansion in the doc pages. It is solved by adding the following in our doc/conf.py:

# This is to tell Sphinx how to print some specific type annotations
# See: https://stackoverflow.com/a/67483317
# See: https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html#confval-autodoc_type_aliases
autodoc_type_aliases = {"ArrayLike": "ArrayLike"}

This way they will appear as literally ArrayLike in the documentation.
