I hate when other apps save the last filter and effects I used. I love love love that camera + doesn't do this. I don't take pictures that are all samey samey, so adding the same filter on every pic is not desireable. If I'm changing the filter and effects for every picture then I'd like to start with normal and filterless. It works well with my work flow. Though, I only use square images on my site, so I'd like to set that in settings and forget it.
