Force screen updating
Not all actions made with the Blender Python API cause Blender to immediately redraw the screen. Therefore, quite often it is necessary to force a screen refresh so that the user immediately sees all the changes.

Checking if system operator was overridden with custom
To resolve conflicts between add-ons in Blender, it may be necessary to know if Blender base system operator has been overridden with a custom operator in some third-party add-on.

Printing text on the 3D viewport area
Using the gpu module from the Blender Python API, we can draw not only images on the 3D viewport area, but also print arbitrary text. Printing text is carried out using the blf module – a wrapper over OpenGL.
Removing vertex colors for all selected objects
Information about the mesh vertices colors is stored in its vertex_colors property, as well as in its color_attributes property. To remove vertex color data from the mesh, we need to clear these mesh properties.

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.
