[Feature Request] : Add Separators for Testnet vs Live Networks

[wakawakathedev]

As a user,

I would like to be able to identify and switch between the networks for the available nodes.

such that I can verify I have selected the correct Active Bank for the network (and update the account balances).

Other than currently naming the nodes in the account manager, (Say prefix with TEST_<node_name>),
there is no alternative method to switch between the live and test networks besides setting the active bank.
