SaintsField is designed to be compatible with other drawers if

1. The attribute in SaintsField does not says "Enable SaintsEditor before using"
2. the drawer itself respects unity-label class to Label for UI Toolkit
3. if the drawer hijacks the CustomEditor, it must fall to the rest drawers

Note about OdinInspector: Odin is IMGUI based with UI Toolkit partly supported. It has label align issue with UI Toolkit. I asked them in discord but never get response. Using SaintsField with Odin, you might see incorrect label width.
