Personally, I see no use for this function, as all your transaction history is registered on the blockchain.
You can simple go to any block explorer such as Blockchain.com (for example) and print the transaction history for all your addresses. No need for this export function.
Thanks for your suggestion. I've known this work-around. With BTC especially its a good way to use the xpub on blockchain.com
But belive me, its a lot of manual work if you have some ALTs and many different addresses...
