<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Sometimes we need to apply update hooks for theme settings, but we can't because themes do not have update hooks. </p>
<p>If we had a "helper" module in the LocalGov Base repo, then we could run updates.</p>
<p>E.G. We want to set the number of items in a Top Tasks list row for services pages to 4 by default. But we also need to run an update hook for existing sites to set it back to 3 - so we don't break existing sites.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Add a submodule - localgov_base_helper - so it's available when we need it.</p>
