It's still on my list to write this, but I thought I would put in a good plug for the tools nonetheless. Ytria tools simply work. And, they save a lot of timeand reduce errors.
Since I do not do much development myself, the two tools that I use the most as part of the QA and deployment for eProductivity are: scanEZ and signEZ. I use these tools to set/reset hidden design and to sign our approved templates before we send them to customers. Other tools like the actionBarEZ and viewEZ and agentEZ are more popular with the development team. The support has been great, too and Andre Hausberger has become quite the champion for us these past few years.
Anyway, if you are a Notes developer looking to improve your productivity, I encourage you to check out Ytria tools.
