Unfortunately, the developers have not yet provided access to the Quick Favorites menu via the Python API in Blender. However, it is possible to transfer the entire menu to the user panel. We can simply draw the Quick Favorites content on the user panel layout.

To work with geometry in Blender using the Python API, it is often necessary to find the center point of a polygon. This may be necessary for organizing various bindings, aligning objects along a polygon, positioning, and in many other cases.
We may need to get the rotation matrix from one vector to another in 2D space, for example, when working with UV maps. This is often necessary to adjust one UV island to another.

To sort the list of materials in the object’s material slots in Blender in the desired way, for example, alphabetically, we can use the function we created earlier to switch materials in material slots.

To move a material from one material slot to another, we can click the up or down arrow button in the object’s material panel. In this case, the material in the currently selected slot will move up (or down) by one position. This method of moving and sorting materials is very slow and not very convenient.

In order to completely select or deselect the entire mesh, it is not enough to change the selection only for its vertices, we also need to change the selection for the edges and polygons of the mesh.

When modeling “by reference”, it is sometimes necessary for the 3D scene grid to be displayed on top of the reference image. This makes it easier to snapping and relate the model being built to the scene as a whole.
When rotating or moving an object using transformation matrices, in some cases we need to be able to extract a part of it from the entire rotation/movement. For example, when rotating an object by 180 degrees, we need to rotate it not at once, but in several steps, each time rotating it by 30 degrees. Linear interpolation of matrices can help us with this.

In order to compare two vectors – to determine whether both vectors point to the same place, we need to compare the coordinates of both vectors and if they are equal, then the vectors are also equal. However, the coordinates of the vectors are specified by float values, the comparison of which for equality, due to the peculiarities of storing this type in computer memory, is never accurate.
From the math course, we know that only one circle can be drawn through any three points in space. So, if we have three points in a Blender scene, defined by the coordinates V0 (x0, y0, z0), V1 (x1, y1, z1), and V2 (x2, y2, z2), let’s see how we can construct a circle that passes through these three points.
