ComponentGrouping for Unity to help with messy inspectors. Odin version to really fix the UX.

ComponentGroup.cs

using UnityEngine;
using Sirenix.OdinInspector;

public class ComponentGroup : MonoBehaviour
{
    // Start is called before the first frame update
    public string Name = "GROUP NAME";
    [InlineEditor,OnInspectorInit("OnValidate")]
    public Component[] _componentsInGroup = null;

    private void OnValidate()
    {
        foreach (var c in _componentsInGroup)
        {
            c.hideFlags = HideFlags.HideInInspector;
        }
    }
}
