Feature request: export conversation to JSON/YAML

[dadanilkin]

Hello, thank you for this promising UI for openai's GPT :)

Could you, please, add a feature to export the conversation into file? Would you like to add such a feature?

If you do but don't have vacant time, please, let me know, I will try to submit it as PR soon (I'm not a JS developer, thus I'm struggling even with such an easy feature :) )
