I want to see each command immediately as it is being executed

[pvbemmelen62]

problem: feedback on the commands only once the table is complete, is too late
I want to see each command (i.e. line in Fitnesse script) as it is being executed. Only once the table is complete, is too late; some tables have many commands, and you have to wait a long time before you get feedback.

solution: show each command as it is being executed
Fitnesse pops up a window at the start of the script, that shows each command as it is being executed.
Maybe it is sufficient if only last n commands are shown.
Window closes when script ends.

alternative: write commands to file, so that a tail command will show it
This would make it more difficult to use because the user needs to start a tail command.
