If there is any interest in that kind of projects, I will add new features, for now it is as it is. It was more like an exercise for me, as I did not work with RPC /remote connection/ never before.
I've been looking for a tool that does exactly this but I didn't find one and am sure many other will be interested in it too. It's gonna be very useful for those whom their addresses got hacked but still receiving transactions.
I read the code and it looks like the created transaction will use the default fee rate (correct me if am wrong). So am wondering if it is possible to let the user customize it according to his preferences or use mempool stats to determine the best fee rate for a fast transaction. In most cases, users will need the transaction to get confirmed asap.
