Feature description

When downloading a video, I am prompted with a filetype (Video/Audio/Subtitles) selection screen. The filetype selection is remembered (previous selection is chosen as default) and affects what options are presented below: video quality, audio format&quality or subtitle language. The video quality selection is remembered but audio always defaults to 128kbps m4a.

Why do you want this feature?

When downloading audio, I either optimise for file size (either 48kbps m4a or 50kbps opus, does not matter that much) or, less often, quality (160 kbps opus). Neither of these is the default option. I would welcome if my last choice was remembered for ease of use, or at least, if a more sensible selection (50kbps opus or 160kbps opus) was chosen as default.
