With Chetan's contributions around the standalone controller, he and I recently chatted about adding a simple UI to complement all the other features now available out of the box.
At Nimbella, we had developed a playground interface for quickly authoring functions (and sharing code) and we'd like to contribute this to the Apache project. I have opened a PR [1] to seed this implementation and have coordinated with Chetan so that it can be used with the standalone controller. You can try it out at [2] if you haven't already seen in and I will show it at the upcoming tech exchange on Wednesday. Feedback as usual is welcomes and appreciated. I have not considered adding this to the rest of the deployments but could explore that. In particular a previous commit added a "/ui" route to the nginx routing in the open source configuration and we could use that for this purpose.
