Dear ChimeraX Development Team,

I would like to extend my appreciation for your continuous work on ChimeraX and the powerful capabilities it offers for molecular visualization.

I previously inquired about the possibility of using static images as backgrounds, similar to what is available in UCSF Chimera. Together, we discovered a workaround by loading an image as a model, adjusting its orientation, and setting it as a static background. However, there is still a significant limitation: when rotating a molecular model (defined in a separate model), the entire scene—including the background—rotates. This compromises the visual experience, as it disrupts the intended static nature of the background image.

I would like to formally request the introduction of a more robust solution that allows for the following:

• The ability to set static images as true background elements that remain fixed when manipulating other models (e.g., rotating or zooming in on molecular structures).
• Support for short background animations, allowing users to load video or animated files that can play while the molecular models are rotated and manipulated independently.

These features would greatly enhance the flexibility and presentation capabilities of ChimeraX, making it easier to create high-quality visualizations and presentations. I believe many users would benefit from these enhancements.

Thank you for considering this request, and I look forward to any updates on the possibility of implementing these features.

Yours sincerely

Enrico
