Changing order of props in input dialog (addon development)

Question

I'm creating addon that adds couple of objects to the scene and I need to control input arguments. Figured out that the best way for me (with almost zero experience with python but 25+ years in other languages, mostly object oriented) is to use existing templates. Two of them that are working perfectly are Addon Add Object and Operator Mesh Add.

I can easily define new properties by adding simple code like this

# my properties

scale: FloatProperty(
    name="Scale",
    description="some description",
    min=0.000001, max=1000,
    default=0.01,
)
clWidth: FloatProperty(
    name="Chain Link Width",
    description="some description",
    min=0.01, max=10000,
    default=12.7,
)
clCount: IntProperty(
    name="Chain Link Pairs",
    description="some description",
    min=20, max=1000,
    default=41,
)

# ... etc

What I'm getting in lower left corner of the screen is input box like this.

What's bugging me a lot are those props outside of red mark atop of dialog. Course, they are important but mostly I don't use them at all. Is there a way to switch their position and put them below my custom properties or somehow collapse them to minimize size of dialog?

I've seen some addons are using different dialogs (the way I like it) but can't figure out how to get different look.

This is an example

Even if there's a way to remove those transform props completely, will be fine because I'm rarely using them and mostly doing all transforms later directly on the scene.

Any suggestions?

You can use options = {"HIDDEN"} to prevent props from being displayed in the default operator layout redo panel.

https://docs.blender.org/api/current/bpy.props.html?highlight=bpy%20props%20floatproperty#bpy.props.FloatProperty

import bpy


class SimpleOperator(bpy.types.Operator):
    bl_idname = "object.simple_operator"
    bl_label = "Simple Object Operator"
    bl_options = {"REGISTER", "UNDO"}
    
    hide_me: bpy.props.IntProperty(options={"HIDDEN"})
    show_me: bpy.props.IntProperty()
    show_me_too: bpy.props.IntProperty()


    def execute(self, context):
        print("done")
        return {'FINISHED'}


if __name__ == "__main__":
    bpy.utils.register_class(SimpleOperator)

Alternatively you can "whitelist" props to be displayed and choose how they will be displayed in the draw method. By default the draw method will display all props that do not have the "HIDDEN" option.

https://docs.blender.org/api/current/bpy.types.Operator.html#custom-drawing

import bpy


class SimpleOperator(bpy.types.Operator):
    bl_idname = "object.simple_operator"
    bl_label = "Simple Object Operator"
    bl_options = {"REGISTER", "UNDO"}
    
    hide_me: bpy.props.IntProperty(options={"HIDDEN"})
    hide_me_too: bpy.props.IntProperty()
    show_me: bpy.props.IntProperty()
    show_me_too: bpy.props.IntProperty()


    def execute(self, context):
        print("done")
        return {'FINISHED'}
    
    def draw(self, context):
        row = self.layout.row(align=True)
        row.prop(self, "show_me", text="SHOW ME !!")
        row.prop(self, "show_me_too", text="SHOW ME TOO !!")
        self.layout.prop(self, "show_me", text="or show me like that")


if __name__ == "__main__":
    bpy.utils.register_class(SimpleOperator)
