ZP is great with some things but when it comes to scraping errors there are rare, errors like the twitter whale or the 'sorry, something has gone wrong' in yahoo. In ubot you can leave the debugger playing on automatic until it reaches the error page, but in project maker you have to click each step and that would mean thousands of clicks to get to your error page. I suggest a project maker that plays on automatic until a step branch doesn't make sense and the project can't be executed. That way, scraping templates can be perfected in ZP.
