Hi Autunna,

To remove thumbnail controls you can use the following code to do so:

```javascript
 instance.UI.disableFeatures([instance.Feature.ThumbnailMultiselect]);

```

This uses the [disableFeatures API](https://pdfjs.express/api/UI.html#.disableFeatures__anchor) and you can find a list of [features you can disable here](https://pdfjs.express/api/UI.html#.Feature)

To add your own customization you can read this answer here: [How can we create our custom thumbnail panel beside our viewer? - #3 by Logan](https://pdfjs.community/t/how-can-we-create-our-custom-thumbnail-panel-beside-our-viewer/811/3)

Cheers,  
Dustin
