What changed, and why.

The first public build. The editor described on the documentation page is in it; licensing arrives with 1.0.

• Your file is written back as the bytes you typed — line endings, indentation, frontmatter and HTML pass through untouched, and every save is atomic. The status bar shows how many bytes actually changed on disk (saved · n B).
• Three views — Live, Source, and Read — of the same buffer. Switching keeps your caret and scroll position.
• Tables are edited in place. Click a table in Live and the grid stays; only the cell with the caret shows its source. Tab, Shift+Tab, the arrows and Enter move between cells, Enter on the last row adds one, and right-click inserts or deletes rows and columns. A | typed inside a cell is escaped for you.
• Math: inline $…$ and block $$…$$, a TeX subset drawn by the app itself. HTML export writes it as MathML.
• Images: paste one from the clipboard and it is saved as a PNG next to your document, in assets/ — only after you press Save on the confirmation card. Drag a handle in Live to resize; the size goes into the alt text (![alt|300](x)), which Obsidian also reads.
• Find & replace (Ctrl+F, Ctrl+H) with case, whole-word and regex options. Matches are highlighted in all three views, inside table cells too.
• Focus mode (F8) hides everything but the text. Move the pointer to the top edge to bring the header back; Esc exits.
• Export to PDF (the Read view's typography, paginated, with the same tables and code blocks as the screen) and to self-contained HTML with no scripts.
• The interface comes in 12 languages, English by default, switched instantly from Settings.
• Korean input is tested on real hardware: Hangul composition through ibus-hangul passes all nine cases of tools/ime_cases.sh. fcitx5 and Wayland are not verified yet.
