Okay, huge suggestion for IP.Gallery in IPS 4: the ability to batch select images and add them to a new album.  

I uploaded some sample images, and now I have no idea how to assign them to an album after the fact.  (My original group permissions didn't allow album creation.)  There are no options to create an album afterwards!  

That's an odd one - being able to upload images without specifying where they would go?

They just went directly into the category.  

I am having this problem aswell. Even with the setting of 'Allow Albums' turned on. It won't allow members to create new albums for their images.

You upload the images first, and then when filling out the details for the images there is a link at the top to add the images to an album (where you can create the album).
