JDownloader has such a weird mix of "absurd levels of automation" and "weirdly many pointless dialogs and buttons to click through"
Like, this thing will automatically open a browser for you and click a CAPTCHA and capture the resulting key and use it to automatically resolve a listing of download links and then grab all the different download sources and check each of them and fetch all their metadata and load-balance requests between them
And then for some inexplicable reason there's no "just download the thing from my clipboard" button, and it explicitly asks you to confirm that you want to continue downloading the file even though one of the many mirrors is unreachable (which doesn't matter)
Just... what
Also, at any given time, about 90% of the functionality works, but it's a different 90% every time
