Hi, everybody! I developed a framework for creating multi-page apps with streamlit!
If you find any bug/possible improvement, please, contact me and send your feedback!
Added new features! Now the framework brings the option of keeping a navigation bar, and the way variables are saved improved a lot!
This component is great! Thanks very much for sharing.
Looks awesome @YanAlmeida , and welcome to the community 
Would you be able to add an animated gif or images of how the navigation looks like at first glance?
Have a nice day!

Sure, Fanilo! A gif running the example file multipage_test.py:
PS: It’s not necessary to use buttons to save the variables. I only did it in the example to show some of the possibilities!
Thank you!
