Beginner's Collaborative Design App with Real-Time Firebase Sync — Feedback Welcome!

Hi everyone!

I have created a beginner-friendly collaborative design app where users can add shapes, text, and other elements on a canvas. The app syncs data in real-time using Firebase, so multiple users can see and edit simultaneously.

What I’m looking for
I’d love your feedback on usability, design, and code structure. Suggestions for improvements or new features are very welcome!
