The “face_strength” parameter is used in the Weighted Normal modifier to calculate normals. We can set and change its values by calling a special operator, or directly getting and setting its values through the Blender Python API.

The Bounding Box is a rectangular box, circumscribed around all vertices of the mesh. Usually, Bounding Box is used for
fast calculations of the physical object’s interaction, for example, collisions.
To display an icon next to a property, text label, or on the operator button in the UI, we need to specify its identifier in the “icon” or “icon_value” parameter. But not all types of icons have their identifiers known in advance. For example, we cannot predefine the icon’s identifiers for procedural textures and materials because they are generated at runtime.
To get the identifier of such a dynamic icon, we can use the “icon” method of the “UILayout” class.
The Eclipse IDE, like PyCharm, and Visual Studio Code, is one of the most popular IDEs for development, including Blender add-ons development. To improve the convenience of developing Blender add-ons in the Eclipse IDE, we can add an autocomplete to it – the code completion for the Blender Python API.
By the Pavel Geraskin tips.

The easiest way to split the user interface into several visual groups is to registers several separate panels in the Blender Python API and merge them by setting the same “bl_category” parameter. In this case, we get some arranged vertically panels, which can be independently collapsed and expanded.
With Geometry Nodes in Blender is easy to create additional custom attributes for objects and transfer the necessary data to them. However, there is no direct access to such created attributes.

There are two ways to create a copy of an object in a scene:

It can be difficult to quickly find and select the scene camera from many other objects in large scenes. However, we can make an operator and assign its call to a hotkey to find the scene camera in a moment.
Geometry Nodes has a node that allows us to remove required vertices from a mesh. This is the “Delete Geometry” node.
With the coordinates of the UV, we can manipulate not only materials but also the geometry of the mesh itself. We can connect the UV coordinates with the mesh geometry using “Geometry Nodes” in Blender.
