You can do ffmpeg -i intro.mpv output.mpv
and when you cursor over ffmpeg it highlights and over output.mpv you can do ctrl+enter and it'll list file contents it should be as easy as if (cursor = word) highlight(word) or if (text->word = text->highlight) show(combo_box) and a customizable profile for commands would be nice, like a scripting language for highlighting and stuff what does everyone think?
