 TODOs
 =====
@@ -59,6 +59,7 @@ This is an informal list of known issues and TODOs:
  * There's some inconsistencies in private vs public attributes of classes. An attribute might've "started" as private and is exceptionally used somewhere else until the number of exceptions is enough for it to make sense to be public, documented and well tested. I'm working on it.
  * neighborlists could be computed much more efficiently
  * There's many other TODOs spread throughout the code
+ * Use `violing plots <https://matplotlib.org/stable/api/_as_gen/matplotlib.axes.Axes.violinplot.html>`_ instead of bars to inform about spread
