Right now you have to specify ignores like this:

[tool.djlint]
ignore = "H001,H002,H003"

More than just being messy, it's also hard to add comments for particular codes. Nicer would be:

[tool.djlint]
ignore = [
    # Ignored because x.
    "H001", 
    # Ignored because y.
    "H002",
    # Ignored because z.
    "H003",
]
