Description

Describe the change. If there is an associated issue, please include the issue link (e.g. "Closes #xxx"). For UI changes, please also include screenshots.

Also move body-related recipe actions to only be in the Body tab. This should cut down on clutter a bit and it's consistent with the actions on the other tabs.
