Overriding the selected objects list for the transform.translate operator
To execute an operator from a context that was not intended for it correctly, it is necessary to override the context for it using bpy.context.temp_override.() selected objects. However, using temp_override, we can override not only the context of the operator call, but also, for example, the stack of selected objects.

Selecting vertices by vertex color
Mesh vertices don’t have a “color” property. Vertex colors specified by coloring in Vertex Paint mode or any other way are stored in an attribute – a separate list of values. To select a vertex by the color assigned to it in an attribute, we need to associate the attribute’s index with the vertex index.

Creating custom icons for Blender toolbar
The common icons used in the UI and operators are packed inside Blender, and therefore we cannot edit or add new icons without a complete recompile of Blender. Icons for toolbars are not tied to the Blender assembly, they are stored in separate files, and we can replace or create and add new toolbar icons.
Getting Blender tools icon ID’s
The ID of the tool icons correspond to the names of the files in which they are stored and they can be obtained simply by looking in the appropriate Blender folder. However, icon IDs can also be obtained through the Blender Python API with the help ot the ToolSelectPanelHelper class.
Creating custom tool in Blender
In Blender version 2.8x and later, a new toolbar has appeared, located in the 3D viewport area on the left side. We can create custom tools and add them to this panel using the Blender Python API.
Adaptive scene metric
By default, all objects in Blender are sized in the same units. However, for convenience, we can use the adaptive metric – small objects will show sizes in centimeters and millimeters, large objects – in meters and kilometers.
