So I am trying to create a Sprite Atlas to save on draw calls.
After packing a lot of images, this “ManTex” tab started appearing on the preview window. I assume this is because there are too many images and they can’t all fit the current atlas?
Does this mean Unity will automatically create another Sprite Atlas to fit the extra images? Or does this mean I need to manually create another Sprite Atlas for the extra images?

SpriteAtlas has the ability to pack all the sprites to one or more atlas textures as required (if sprites don;t fit to single texture). The textures will all be part of the same SpriteAtlas and sprites will correctly reference these textures on the Runtime irrespective of the number of textures in the same SpriteAtlas.
So, technically it’s possible to just have a single SpriteAtlas for the entire project and this will just work fine.
However it’s a good practice (as well as good for performance and load times) to categorize sprites and create multiple SpriteAtlases (for example based on Categories, Scenes, Levels, Characters, Animation etc…) to achieve better performance, reduced memory and load times.
