It is great to have OS taking it on. The ability to add content to child menu items is fantastic. This tool helps us to quickly set up our site information architecture and add notes about content or dummy content with ease.
I contacted the developers with an issue and they responded quickly. They also personally emailed me to alert me to the fact that they had released a new version, certainly not something I expect, but as I had had recent contact with them it was a very nice thing to do.
