Creating a Custom Properties Tab in Blender 2.80 I have a suite of several addons that I grouped together in a custom tab in Blender 2.7x, assigning the bl_category to the name of my custom suit:

class Panel1(bpy.types.Panel):  # Blender 2.7x
    bl_label = "Panel 1"
    bl_space_type = "VIEW_3D"
    bl_region_type = "TOOLS"
    bl_category = "MyToolSuite"


In Blender 2.80, I would like to group the tools together in a new properties tab.  How can I create a custom properties tab?

The following works to put my panel inside an already-existing tab, but does not work to create a new tab to hold all my panels:

class Panel1(bpy.types.Panel):
    bl_label = "Panel 1"
    bl_space_type = "PROPERTIES"
    bl_region_type = "WINDOW"
    # bl_context = "object"     # this puts my panel in the Object tab
    bl_context = "MyToolSuite"  # this does nothing?


What else needs to be done to create a new tab in Blender 2.80?

Thanks!
The code you've posted adds a tab to the Tool Shelf, not the Properties. As far as I know you cannot add new tabs to the properties, you can however add tabs in the 3D View.



In Blender 2.8 you need the following attributes to create your own tab:

bl_category = "Name of your tab"
bl_space_type = "VIEW_3D"
bl_region_type = "UI"


A minimal add-on that adds a panel in a separate tab:

import bpy

class EXAMPLE_PT_panel(bpy.types.Panel):
    bl_label = "My own addon"
    bl_category = "Name of your tab"
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"

    def draw(self, context):
        layout = self.layout

        layout.label(text="This is a label")


classes = (EXAMPLE_PT_panel,)


def register():
    for cls in classes:
        bpy.utils.register_class(cls)


def unregister():
    for cls in classes:
        bpy.utils.unregister_class(cls)

if __name__ == "__main__":
    register()
