Feature Request : Shortcut for Vertical view for list of subtitles

Unlikely that one Korean, Chinese, or Japanese character indicates one syllable, an English character indicates only half or one phonetic sound, so a sentence in English is often as long as two, three, or even four subtitles.

In this reason, I often use the 三 button to the Vertical view for list of subtitles of the screenshots very much in case that one subtitle does not contain a whole sentense.

Therefore, I need a shortcut for opening Vertical view for list of subtitles; hopefully, if you also add merging subtitles feature like any other mobile language learning apps, too, it would be the best.
