Years back, I took a small whack at an idea that had been percolating in my head: a "app manager" application that would assist with the XPage-specific portions of running a Domino server. It would cover a lot of ground that Administrator really doesn't touch, such as inspecting NSFs to see which contain XPage artifacts, highlighting potential problems with them, and assisting with app-design backup and deployment.
It never really got too far, since there are always a hundred other things to work on, but I always liked the idea. I decided to toss what code I had laid down up on GitHub:
I don't imagine I'll really have time to build on that unless I'm suddenly really struck with inspiration. But either way, the code is there for anyone interested in taking a look.
