 - ASB + CONTROLLER: Add a `monero_seed` command to the controller shell. You can use it to export the seed and restore height of the internal Monero wallet. You can use those to import the wallet into a wallet software of your own choosing.
 - GUI: You can now change the Monero Node without having to restart.
+- GUI: You can now export the seed phrase of the Monero wallet.
