Feature request: Dictation

Needs dictation feature to improve listening skill or memorizing sentences with proper shortcuts and built-in dark color notepad.
For example, WASD are for subtites, and →←↑↓ are for cursor on notepad in LLN; Other shortcuts are for notepad and subtitles to appear/disappear; Everything is in one LLN window.

Currently, I’m using Windows notepad, but it’s not productive. I want LLN to add dictation feature.
