When we want to see how specific action works, we just double click on this action i repository explorer (no changes in filesystem are made). When it comes to Constants and Structures, we need to first move models to developing space and then we see what it contains (in case of big structures - usually not). Disadvantage is we make changes in filesystem this way and it's longer way.
So it would be nice if we could see those Constants and Structures in similar way (double click) as we can look at actions.
