A double click on a dataset from inside the Server List both puts a that dataset's shortcut in the current process flow and opens the dataset in a current view window. Some datasets or views take a long time to load; for instance- SASHELP.VTABLE, especially when a user has many files and LIBNAMEs defined.
Please add a button and/or a shortcut key that will cancel the current loading of a dataset into the viewing window, leaving the behavior of adding the shortcut to the process flow as is. A message displayed in the window stating that the loading operation had been cancelled by the user would be proper to have if such a loading was cancelled.
