It would be great if you could just right click on a UTXO and select something in the lines of "Put UTXO in the Badbank". Any UTXO could potentially turn doxxic for whatever reason (e.g. you catch someone taking a picture of your screen behind your shoulder in a cafe, getting doxxic change etc...). So, when in doubt, you could just put any UTXOs in the Badbank yourself and mix it later.
The current workaround would be to send the doxxic change/UTXOs back to yourself on-chain, and mix it then...but that involves more fees.
