A rival bot creator software has a commercial PHP scripting plugin ($60).
1) Having the option to script with PHP as a feature in the Elite and Developer editions of Botchief would be amazing and really useful.
2) The Curl command line as options would be an amazing feature so you can have it run from inside a bot without having to run it externally since that would require bot users to download and install it. I know a lot of what Curl allows can be done with botchief however it is a lot more complex and since Curl is very popular there is millions of command line examples shared online doing all sorts of things so it would be really useful.
3) The ImageMagick command line would be very useful also. A quick example usage would be a image scraper bot that instantly resizes and applys a watermark to each image as it saves them to a users computer.
