I write in google drive spreadsheets (because they're scripts). I can't show a screenshot because I'm sure my boss wouldn't like it, but it's your basic spreadsheet with character names and descriptions in one column, dialogue in another, and programming in the third and fourth columns. When I first started writing this way, I found it realllly hard to read because you have to follow multiple columns at once, but I've grown used to it. It's also available on any computer connected to the internet, which is a bonus.
