I suggest allowing the use for files to use with Codex to make longer code for translating or feeling out information. Also would be nice to use this for sending data in as an example to build code around for editing and display.
Did you try using the Python API for longer code? I am curious to know how that went.
I setup a Python script that i can use the API. But it says 4000+ characters is allowed, but 3000 seems to be the actual limit. But i would like to setup a template file and have Codex chain to it. To create a version of the file with Codex filling in the blanks. This came up when I was trying to setup a script to read a json file that was to long.
