9- [ ] make it one click to branch off like old jp townie demos
10- [ ] opentownie as a pr bot
11- [ ] give it the ability to see its own client-side and server-side logs by building a middleware that shoves them into a SQL light database date and then give it a tool to access them
12- [ ] do a browser use or screenshot thing to give it access to its own visual output
13- [ ] Have it default to creating a new branch off main
