Hi @mmcky , the first issue I noticed by comparing downloadable notebooks from ``RST`` and ``MYST`` is that - the QuantEcon brand is missing in all notebooks from ``MYST`` For example, please find a screenshot for lecture ``02_multi_hyper`` (left: ``RST``, right: ``MYST``):  It occurs in ``MYST`` because notebooks from ``MYST`` do not have the following code at the place of the brand: ``` <div id="qe-notebook-header" align="right" style="text-align:right;"> <a href="https://quantecon.org/" title="quantecon.org"> <img style="width:250px;display:inline;" width="250px" src="https://assets.quantecon.org/img/qe-menubar-logo.svg" alt="QuantEcon"> </a> </div> ```
