Focus mode & Animations

[whodame]

Add a focus mode with nothing but a text editor, plus a timer and background music feature like in Calm Writer.
Make the text writing animation smooth.
Add customizable transparency, separately for text and UI elements, as well as the ability to set a background image and change the text layout, like in Focus Writer.
After that, it will be the best word processor with MarkDown support, except for Obsidian (but it will still be heavy, slow, and there are no animations).
