Auto Render Slots & Thumbnail View for Render Comparison

Dear Blender Development Team,

I would like to suggest a feature that would significantly improve the workflow when rendering images. Currently, rendered images overwrite the previous render unless a new render slot is manually selected.

It would be highly beneficial if each new render automatically generated in a new render slot. Additionally, having a thumbnail view of previous renders available below the render result would allow users to quickly compare multiple renders without needing to switch slots manually.

Thanks for the wondreful work so far on Blender and keep up the good work!
