Would like the DEBUG window to be more usable. Like in code:
Debug.print "OKAY"
debug.cls
debug.Switch DebugWindow1
Debug.print DebugWindow1, "this is window one"
debug.Switch DebugWindow2
Debug.print DebugWindow2, "this is window one"
debug.DumpToOutfileFile DebugWindow2, "Testcase_history.txt"
debug.DumpState "files / directory"

Then you can do 50 things at once if some of the above was implemented. Maybe even an explorer for the results of the Debug tool.

And, be nice to have different debug levels:

Debug.print DebugLevel1, "nothing to worry about"
Debug.print DebugLevel999, "better fix this problem now"

And, these never show during the final distribution edition.
