In this section, we will create our plugin and related code.
We will follow the top-down principle in development. We will start with big blocks and then go into details. We will use small functions that call other small functions to perform isolated functions. This creates cleaner applications that are much easier to debug, and it is much faster to fix or re-implement any functionality, if necessary.
Before we proceed with implementation, we need to create several additional files. We will use these files later during implementation. Generally, if a feature is used, it is better to have a skeleton of such files created in the very beginning. Later, information can be simply added there when necessary. There will be no need to be distracted from the main development course to create these files from scratch.
