Sea 0.2.1-beta.1
Highlights
Locked notes are simpler: unlock one note at a time, lock a single note without touching the rest, and lock everything from Settings when you want to.
Bring your writing in and take it out: Sea can now import and export Markdown.
Mermaid diagrams render is here!

Improvements
Locked note previews use clean redaction bars instead of blurred placeholder text.
A performance pass makes the note list, search, and startup feel quicker.
The outline stays steadier while you scroll and type.
Formatting and selection tools in the editor behave more consistently.
Fixes
Underline ranges for tags and links now keep up while you type.
Link syntax matches your text instead of switching to a typewriter font.
Jumping to a heading from the outline no longer moves your cursor.
