using nodes to create widgets can be used to add plugins to widgets estuary but should work with themes that use the widget

there are two types you can set up
WidgetListCategories is where you goto the folder library://video/widgets/skinsearch/row1
WidgetListPoster is where you goto the xml fole library://video/widgets/skinsearch/row1/row1.xml

you need to create node

xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<node order="20" type="folder">

 <label>575</label>

 <icon>DefaultInProgressShows.png</icon>

 <path>videodb://inprogresstvshows/</path>

</node>

then you do the widget to the way you need it

xml:
<include content="WidgetListCategories"  condition="Skin.HasSetting(HomeMenuNoswr1Button)">

       <param name="content_path" value="library://video/widgets/skinsearch/row1"/>

       <param name="widget_header" value="row1"/>

       <param name="widget_target" value="videos"/>

       <param name="list_id" value="30100"/>

       <param name="icon" value="$VAR[WidgetStudioIconVar]"/>

       <param name="icon_height" value="70"/>

       </include>

      <include content="WidgetListPoster" condition="!Skin.HasSetting(HomeMenuNoswr1Button) + !Skin.HasSetting(swidget1poster)">

       <param name="content_path" value="library://video/widgets/skinsearch/row1/row1.xml"/>

       <param name="widget_header" value="row1"/>

       <param name="widget_target" value="videos"/>

       <param name="list_id" value="30101"/>

       </include>
