This appears to work fantastically. I just need to do some thorough testing and I'll merge this today.
This is so cool

I made one minor change that sends the user to the uart output screen when they press back from the dialog. The reason why I chose to go there instead of the main screen is to allow for the user to view the current session's incoming requests without having to reset the portal if they accidentally press back.

Everything works so well, really great work! Merging this now.

I wanted to give a heads up, I moved this code to the dev branch and pulled it out of main. I only did this because some firmwares pull the latest main branch automatically into their latest builds. This will be released with 0.0.3!
