Spike: 3Dmol.js UI controls

[SebastianIsSeabass]

As a user, the small and full screen view of the 3D molecule doesn't include and instructions or button to guide use. How do I pan, how to get out of full screen, how can i zoom in or out?

Determine if 3Dmols.js has a set of UI control or instructions that can be turned on to help users understand how to use the viewer.

Ideally we would not need to do any (or very little) custom design/testing to include some help for the user.

Acceptance Criteria:

We have determined if 3Dmol.js has built-in controls or user instructions. Or if they can easily be added in some way

3Dmol doesn't provide built-in support for displaying user instructions, but the full list of supported mouse gestures can be found here: https://3dmol.csb.pitt.edu/doc/index.html#mouse-controls. It should be straightforward to display these in a custom popup.
