Subflix от hyvyys

With a single click or keystroke you can:
◆ show/hide a live subtitle history — recent subtitle lines displayed in a smaller font on the side of the screen to let you focus on the speech: [z] or right-click on the left half of the screen; by default, 3 lines are displayed, but you can scroll up with the mouse wheel to see the previous ones; the history disappears in 5 seconds after adding a subtitle, unless the mouse is hovering over it;
◆ hide/show the regular subtitles (without rebuffering that sometimes occurs when subtitles are switched manually): [x] or right-click on the right half of the screen,
◆ switch the language of subtitles (this is only a shortcut to the regular Netflix switch): [c].

Go to Addons page to change settings such as:
◆ the keyboard shortcuts,
◆ the number of subtitles displayed in the history,
◆ the time delay after which the subtitles are displayed in the history,
◆ subtitle history font size.
