Margen Beta 6, the final version. Three new features.Folders with colors. You can create folders (subjects) and assign notes
to them. Each folder gets a color from a preset palette. The sidebar
shows a folder list above the notes, click a folder to filter. A
selector in the editor header lets you assign or change the folder of
the current note. Useful for organizing by subject: Calculus, Physics,
Programming.Linked notes. You can now link notes together using double brackets like
[[Note Title]]. The parser finds the note by title and creates a
clickable link in the preview. Click it and the linked note opens. If
the note doesn’t exist, it shows in red with strikethrough. Useful for
connecting related topics across subjects.Formula OCR. A camera button in the editor header lets you upload a
photo of a math formula. Tesseract.js extracts the text and a basic
converter turns common math notation into LaTeX: ^ becomes ^{}, sqrt
becomes \sqrt{}, int becomes \int, Greek letters get backslashed, etc.
The result is inserted at the cursor wrapped in $$ for block math. It’s
not perfect OCR (Tesseract is designed for text, not math) but it gives
you a starting point that you can edit manually.Calling Margen complete. Six betas across editor, parser, cheat sheet,
LaTeX, dark mode, i18n, code highlighting, PWA, import, export,
onboarding, shortcuts, focus mode, word count, folders, linked notes
and formula OCR.
