When the user manually resizes the window by dragging the bottom border more toward the top, the download will eventually disappear as the current content shown will simply be cut off. It would be better if only the list of available downloads would be cut, a scroll bar appear to make the missing list elements appear on demand and the download button would be shown at all times, no matter in what way the user resizes the window. This becomes especially a problem when the user first enters a youtube link with few available downloads and afterwards enters a youtube link with many available downloads: the download button will disappear by itself by being shoved out of the shown window by the long list.
