A wish, if I may -- A stop statement should print line number, such as "Break in 9760" rather than just "Break", similar to "Breakpoint in 9760" with Break command. When debugging complex code, I use Stop statements and breakpoints, and now knowing which Stop has been reached is annoying. Ok, I can run it with Tron, but it's not always convenient...
Alternately, if Thoreau Machine Explorer had a way to display current call stack and break location in break mode, that would also be convenient!
While on this topic, breakpoints list is not cleared when loading a new program. At first I'd called that a "bug", but repeatedly loading the same program edited in an external editor during a debug session and keeping the list of breakpoints is convenient... I'd now call that a "feature" :-)
