allow to filter accounts by site, not only by network

[X] Feature request

If I expose this extension to a site, that site could potentially learn about all my wallet addresses (I have to trust the site that my data is only processed client side). This is a severe privacy risk

I'd like to select per account:

• what network(s) to use the account on
• what sites are allowed to see the account

talisman does the latter, but not the former. And - it's not open source (yet?), so it is no option for me to use it

I don't think you can have the account by network since the extension is not aware of the networks the dapp is connected to.

As for the which account per website, this feature is implement since #1068 but there has been no public release of the extension since then.
