Hi Adam :
We have the requirement of adding custom label to the toolbar. The intention is to show the character count in the toolbar. The following are the changes I did but it didn't seem to work and render the label on runtime. We are using version 5.0. We have a custom config file like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <contextmenu>
  <!--<item name="Editing" value="True"/>
  <item name="Format" value="True"/>
  <item name="Insert" value="True"/>
  <item name="InsertAdvanced" value="True"/>
  <item name="InsertFiles" value="True"/>
  <item name="InsertForms" value="True"/>
  <item name="Relative" value="True"/>
  <item name="Tags" value="True"/>
  <item name="Verbs" value="True"/>-->
 </contextmenu>
 <toolbars>
  <item type="g_start" />
  <item type="image" name="Cut" />
  <item type="image" name="Copy" />
  <item type="image" name="Paste" />
  <!--
  <item type="image" name="PasteText" />
  <item type="image" name="PasteWord" />
  -->
  <item type="image" name="Delete" />
  <!--
  <item type="separator" />
  <item type="image" name="Find" />
  -->
  <item type="separator" />
  <item type="image" name="Undo" />
  <item type="image" name="Redo" />
  <item type="separator" />
  <item type="image" name="Bold" />
  <item type="image" name="Italic" />
  <item type="image" name="Underline" imagename="under" />
  <item type="separator" />
  <item type="forecolor" />
  <item type="backcolor" />
  <item type="separator" />
  <item type="holder" name="MyHolderName" />
  <item type="g_end" />
  </toolbars>
</configuration>
