On a related point, I used to make great use of a plugin shared on the forum years ago called 'ReadTextFromFile' or something very similar to that. I can't remember who shared it originally but it was great. It allowed you to read a plain-text file line by line, so was perfect for titles, captions, etc and you could edit the text in a text friendly package that could be easily shared with writers/directors etc.
I guess now that work flow could be replicated with the Data Array actor. You could also use it to record and recall other settings, such as font size, colour, position all stored in the same tab-seperated text file. The file could be easily shared and edited by other people as well.
