I'm using your 96 slot backpack with food/water bars along with your 10 slot toolbar. Thing is I still get the food and water bars under the toolbelt. This makes the toolbelt overlap the back pack window slightly. I'm pretty sure the bars are being added back in by the 10 slot toolbelt. Is there a version of the 10 slot without the default bars?
Edit
Took a stab at it and was able fix it. Here's what I did:
<configs>
<append xpath="/windows">
