When new users are first trying to navigate through the work flows and they want to Check what is information is going to variables, a view of sorts would be a good addition.
For instance, Start process > Get OutLook Messages which saves into a List variable.
Now if you ran this you wouldn’t have any idea really of the make up of this list ie what information is available to use with out doing some searching on the net.
If you could run the above and be able to click somewhere to be able to view the list with column headings and the data I think that would be really handy.
