Hi Plutus Pioneers! 
It is possible to interact with contracts using datums and cardano-cli. It is possible to send tokens to smart contracts with any wallet.
But which wallet: Deadalus, Yoroi, Nami, Flint, Eternl or any can interact with smart contracts directly and using datum without third party application that uses cardano-cli?
Would love it, but have never seen it.
In principle, they, of course, could. If a dApp connects to it, all except Daedalus do smart contract transactions perfectly well.
But none of them has a UI to build such transactions. They are just able to get it through the dApp connector.

Doing some self-advertisement. I was annoyed of using the cardano-cli and thus created a transaction editor to simplify that process, it ended up becoming a wallet on its own.
I recorded some videos showing it, maybe that workflow fits you well.
Definitely, your wallet addresses the question I raised Cardano Wallet interface and Spending from Scripts - YouTube
