@ajb2k3 Yes, I knew about it. But I think that @hkubota was after is a little different. Maybe to have a way to start designing the ui of the app in UIFlow and then add specific functions in python editor. At least this is what I'm doing. So it would be good to be able to save the blocks and the code separately, and then you can either apply the changes (like a file diff) or not.
In your picture, the “/“ looks strange (it is touching the text) and not like mine. Perhaps you copied and pasted the feeds path from the Adafruit dashboard into UIFlow and it added some other character that looks like “/“ but is not truly a forward slash. Not entirely sure, but glad you got it working.
