1. Give the possibility to capture directly into Hollywood the executed program output
captured_output = Execute(program_name)
2. Implement the possibility to attach a callback for every line captured from the executed command
I don't know if this is easy or not to implement but could be really usefull, for example when launching a program that do long tasks and print out the progresses of the elaboration (encoders, archiver, and so on are good examples)
