Great

Great. Did exactly what I wanted and simply. I had previously made the mistake of buying a competing app which was more expensive (lingon). I was rather dissapointed and a little annoyed to be honest that I had not found this app sooner. Oh well you live and you learn!

Tip: If you want a simple to use LaunchD app with lots of functionality this is the one.
I would personally say avoid LINGON.
