Maybe you read too fast x)
Next version (1.8) with packaged releases is almost ready.
Install process will be much easier.

I've been using both extensions almost every day for more than a year without getting banned, but there is always a risk.
Since the code is running inside a real browser, it might be more stealth than command line tools, not really sure about that.
Original tidal-dl-ng had a delay option to wait between tracks downloads, maybe i'll implement the same feature.

From the streaming service like other downloaders.
Main differences : it does not need credentials (attached to browser session), and no additional software required.
Just the web extension. And bugs.

Nope, downloading the same albums countless times when debugging the code did not trigger any lock-out mechanism. But there is always a risk. And a disclaimer.

Haha yes of course it is. These services are very nice indeed. I'm a little bit confused to get audio files from "official" services instead of good old hi-res music websites x)
