 Features:
 * Jupyter extension to format matrices in cell outputs.
-* A `__repr__` monkey patch to format matrices in the Python shell.
-* Nested sub-matrices of any supported type, including mixing packages.
 * Configurable float precision or format string.
 * Toggle row and column indices or set your own labels.
+* Nested sub-matrices of any supported type, including mixing packages.
 * Toggle matrix description or set your own title.
 * String output can optionally autodetect terminal width.
 * Methods to directly display a matrix (`mprint`, `mdisplay` for Jupyter)
 * Methods to convert to string (`to_html`, `to_latex`, `to_str`).
 * Configurable per method call or set defaults with `matrepr.params`.
+* A `__repr__` monkey patch to format matrices in the Python shell.
 * Fast.
