Consider zajsf fork for plugin layout
### Feature Description

Is there any way we might consider moving off of [ajsf](https://github.com/hamzahamidi/ajsf) for plugin layout support? We're unable to nest arrays and have the results show up unless we abandon the "layout" option available in ajsf (https://github.com/hamzahamidi/ajsf/issues/144). It does appear that this fork is more up-to-date and has been applying various patches to make our lives better [zahmo/zajsf](https://github.com/zahmo/zajsf). Thanks to @zahmo for picking this one up.
