I think the Service studio has major usability problems. One thing i'm noticing is that there should be a way to switch between action and screens in a faster way.
Imagine you are developing an action based on other action. If 2 tabs were open with each action the developer could easily switch back and forth and develop faster.
The way one has to do right now is constantly open each action, navigate to to desired SU, check its properties and then go back to the other action and do the same. This is extremely time consuming because of the time i it takes to to this procedures but also (and more important too) because i loose focus during the process. I'm not entirely focues on the task i have to do, but also on the constantly switch of environement.
I think it woud be a great addiction to the service center and fairly simple to develop.
