Currently the Camera Mode sub menu is ordered as follows:

Local Photo | Gallery Photo | User Icon | Multi Layer | Emoji | Animated Emoji | Animated Emoji

This sorting feels a bit wrong as you essentially have:

Local Stuff | Gallery / Icon | Local Stuff | Emoji Stuff

Which feels a bit unorganized to me.

Move the "Multi Layer" button to the right of the Local Photo button, so that the sub menu would be organized like this:

Local Photo | Multi Layer | Gallery Photo | User Icon | Emoji | Animated Emoji | Animated Emoji

Doing this would essentially split the Camera Mode sub menu into 3 sections:

Local Stuff | Gallery / Icon | Emoji

If you want to be real fancy you could even add some separation lines between these 3 sections :D

Here is a picture showcasing the issue:
