Hi Autunna,

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

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

This uses the disableFeatures API and you can find a list of features you can disable here

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
