Hey there,

Unfortunately we do not have a good way to do this right now.

We are working on our UI customization APIs and will hopefully have more flexibility in the near future.

However, please note that our UI is [open source](https://github.com/PDFTron/webviewer-ui) and can be customized however you wish by editing the source code. We have a guide on doing this [here](https://pdfjs.express/documentation/ui-customization/advanced-customization).

Thanks!  
Logan
