A Flask webapp to draw tkinter sketch and create a .py wireframe file

[tzebre]

Hello everyones 😁
I have some friends who are experiencing a really hard time setting up a Tkinter app layout. So, I'm developing a Flask app to help them.
The goal is to create a sketch of the app by drawing rectangles and specifying the widget types. Once the layout is saved on the web app, a Python file will be generated using Jinja. This file will contain all the code needed to reproduce the sketch from the web app.

All the code is open source and available here (work in progress). I apologize for the lack of thorough documentation at the moment. However, if any of you have ideas to improve it, I would be delighted to discuss them with you.

Go from this sketch:
