feature: forget or deleted multisigs created

[muddlebee]

currently I created a few multisigs to test, but can't delete :| how can I ? I dont see any options in settings to remove or forget.

I was also expecting an option to wind down the Vault. It is stated on https://guide.polkadotmultisig.com/en/category/setup/article/creating-a-vault that the deposit can be refunded when you wind down your Vault, but there appears to be no UI to do so?
