Include script writing software in your Office suite.
As easily accessible as Word or Excel, I'd love to have script writing software that could automatically format screenplays, plays and other writing that has traditional structures and formatting. It could be an added tab in the Word program, like Design or Layout (or even included within those tabs). Final Draft and CeltX offer things like "index cards" and other accessories to help with plotting but I'd like something that is just concerned with the actual script, to reduce distractions and also make me feel less in need of learning how to properly use all the accessories. It could work with keyboard shortcuts to dictate which part of the script (dialogue, action, character, headings etc) is being used or even be as laborious as selecting it from a tab at the top. I'm sure the actual programmers would have a better idea of how to make it work smoothly.
