In the future it would be nice to see:
→ Total value from all Wallets
→ Chart that represent historical changes of the balance in fiat
→ Value Decomposition: by type (Available, Locked, Staked etc.), by wallets value (50% Wallet 1, 50% Wallet 2), by different tokens (15% in DOT, 10% in KSM etc...)
Zerion does something similar
