In the Blender Python API, a collection does not have a direct pointer to its parent collection. However, we can get the parent collection by searching through the list of children of each collection in the scene until we find the current one.
Filtering values available for selection through the UILayout.prop()
When creating custom properties, the values of which the user can choose from a list, it is often necessary to filter the list of values offered for selection. We can use the poll function to shorten the proposed list of values by removing unwanted elements.

Showing text in the area header in Blender
When executing modal operators such as rotation, translation, or scale, text with the current values of the mesh parameters being changed is displayed in the header of the current area. If necessary, we can display any required text in the area header.
Making collection active
We can’t set a collection active through the Blender Python API in one step. The “bpy.context.collection” property is read-only, and the “bpy.context.view_layer.active_layer_collection” has a “LayerCollection” type that cannot be set with the standard “Collection” type. To assign an active collection, we need to find the View Layer collection from the desired base collection and already set it as active.
Changing mouse cursor in Blender
One of the common hints to get the user attention when performing certain actions is the changed appearance of the mouse pointer. In Blender, using the Python API, we can set the desired view for the cursor when we need.
Hidden textures in Blender
To make a texture hidden in Blender so that it does not appear in the list of textures when selected in the Image Editor and is not found through the search, the texture name needs to start with a dot.
Placing the image selection block on the user panel
In Blender, the block of buttons for selecting an image in the Image Editor is placed in the header of the area by default. If necessary, it can also be placed in the user panel.

Converting mouse cursor coordinates from area to texture coordinates in Blender Image Editor
In some tools, for example, “eyedropper” or “selection by color”, it is necessary to get the value of the texture pixel that is currently under the mouse cursor. To get pixels data we need to know its coordinates in the texture space.
Locking the mouse cursor within the area in Blender
Sometimes it may be necessary to prevent the mouse cursor from going beyond the boundaries of a particular Blender area. For example, when grabbing and dragging a mesh with the mouse, the captured mesh should not leave the 3D Viewport area, not to be above another type of area, for example, above the Node Editor or Text Editor areas.
