Show current network on main page of the wallet

[leohhhn]

Hey @onbloc team, love the work on Adena.

I found a small improvement that could be added to the Adena UI: having an indicator of what network you are currently connected to (ie staging/test3/.../mainnet) on the main page of the wallet.

IMHO, this is an important piece of UI when using the wallet. What do you guys think?

@leohhhn, thank you for suggesting this – it's a great idea. Maybe we can display the connected network on top of the main UI for all networks (staging/test3/...) except the mainnet. This would give a cleaner, more official UI to the mainnet, while still indicating clearly which network users are on when not on the mainnet.
