Very often a download "freezes", with what i mean: iit shows that download arrow, but the loading bar is freezed, the bandwidth shown next to bar disappears and you can not pause it (i pressed the pause button or used pause all a hundred times, its useless in this case) and it never does anything else but stay that way until its deleted
maybe its only on macOS and doesn't occur on windows, but still you definitely need to fix this bug
it often messes up my download of huge lists (100+ videos) and really think about changing to another download app because of this
