Debugging a program twice appends 1 to the session name in the Debugging window combo which is not obvious when that name ends with a number (eg JavaApplication1, shows as JavaApplication1 and JavaApplication11). It would be easier to read if there was a space between the session name and the number. "JavaApplication11" could become "JavaApplication1 1" or may be better "JavaApplication1 - 1"
Created attachment 147100 [details] a patch that enables the later option "JavaApplication1 - 1"
