Created a sub-address "tool" a while back and I've been using it for myself. Zano doesn't support sub-addresses natively so this tool when run will automatically create a new Zano Wallet "temp-wallet" and print the address in a command prompt. You can copy this address and send Zano to it, then the script will automatically direct those funds from the temp-wallet to a "MAIN_ADDRESS" which you can set as whatever you'd like.

So effectively sub-addresses.

Here's the github if you're interested: https://github.com/acf-script/zano-subaddress-sweeper

This script has potential for abuse only use the original script I created in the event someone forks it. Line 257 is the place in the code that determines where the funds are sent, you can verify yourself that "address" is MAIN_ADDRESS.
Always worth doing a test transaction with a small amount of Zano to ensure everything works properly.
Check out the readme before using.

If there are any other tools/scripts/programs that people want made on Zano I'd love to try to make them. Reach out to me, comment under this post I'll see what I can do.
