[fubuloubu]

• Add a strategy (by address, using pre-defined params w/ overrides available)
• Update params for strategy (single parameter or multiple params at once)
• Revoke a strategy
• Manage withdrawal queue (reordering, adding, removing)
• Allow "batching" multiple actions together using MultiCall
• Add a method to "delegate to" another account for execution (such as Gnosis Safe)

not really, could complement CMO actually if it were published as a package separately that we could use in a management script, which could be used to deliver transactions to multisig
