Application Development good first issues

This GitHub issue requests the addition of "Sani Optik," an optician located in Serbia, to a system or list. The issue provides the company's website for reference, likely for data extraction or verification.

Debug and fix a bug in TrayToolbar version 1.5 where the `desktop.ini` file, responsible for custom icons, is unexpectedly replicating into top-level folders. The issue arose after an update from version 1.4 and only affects top-level folders in the selected toolbar directory. The fix requires investigating the code changes between versions 1.4 and 1.5, identifying the source of the unintended `desktop.ini` file creation, and correcting the behavior to prevent replication.

Refactor the Formello package's field configuration to use a more fluent and Laravel-like builder pattern. This involves changing how field options are defined, transitioning from a simple associative array to a chainable method call approach using a new `FormelloField` class (or similar). The goal is to improve readability and maintainability of form definitions.

Correct a typo in the README file of the `websockets/chat-tcp` example within the Actix Examples project. The typo is an extra backtick in the command to run the websocket-tcp-server.

Add a new Java-focused quiz section to an existing HTML, CSS, and JavaScript quiz application. This involves creating new quiz questions, potentially modifying existing code to handle the new quiz data, and ensuring a smooth user experience within the existing application's design.

Enhance the existing quiz app's "Check Total Score" functionality to display a comprehensive quiz summary instead of just the raw score. The summary should include the score with percentage, correct/incorrect answer counts, a motivational message based on the score, and buttons to retry the quiz or return to the homepage.

Create a Code of Conduct file (Code_Of_Conduct.md) for a simple quiz web application. The Code of Conduct should outline expectations for respectful and honest participation, prohibiting cheating and offensive behavior.

Add an MIT license to the Quiz App project. This involves adding the standard MIT license text to the project's repository.
