Is it possible to make changes to the source code of the framework you are using?

Yes, it is possible to make changes to the source code of the used framework, especially if it is open source. This allows:

• Fixing bugs that hinder operation.
• Adding new features or improving existing ones.
• Adapting the framework to specific project tasks.

However, it is important to consider:

• Changes may complicate future framework updates, as you will need to manually transfer your modifications.
• It is important to comply with licensing agreements.
• It is better to first check if there are already ready solutions or official ways to extend (for example, through plugins).

Example: if you are using a Python library and find that it does not support the functionality you need, you can clone the repository, make changes, and use your version, or propose a pull request to the original project.
