Sparrow is horrible for newbs because it leaks your entire wallet history to chainalysis servers by default.

Sure. Any public Electrum server can potentially be monitored.

I hope that a future redesign will move this away from the main screen so it won't bother people who don't coinjoin.

Yeah, my concern was that newbies might get overwhelmed.

Do you have any recent examples of this happening? I've coinjoined for years and never had any funds blocked.

Not super recent but late last year some shitcoin chain bridges (BTC to USDC) blocked coins from Wasabi. I would assume it hasn’t changed.
