Markdown Vault — New Storage Engine

This is arguably the most significant update in massCode's history. You can now store your snippets as plain Markdown files directly on disk.

Why it matters:

Your data is just files. Each snippet is a .md file with frontmatter metadata. No database, no binary formats. You can read, edit, and organize snippets with any text editor or file manager.
Git-friendly. Store snippets in a Git repository, sync via GitHub, track change history — everything works out of the box because it's just files.
Cloud sync. iCloud, Dropbox, Syncthing — any file sync service will do. No database conflicts.
Live sync. massCode watches the vault directory in real time via a file watcher. Edit a file externally — the app picks up changes automatically.

How it works:

The vault structure mirrors your folder hierarchy. Each folder is a directory on disk, each snippet is a .md file inside it. Metadata (language, tags, order) is stored in frontmatter, while .state.json handles UI state (expanded folders, sort order).

You can switch between SQLite and Markdown Vault in Settings → Storage.

Custom Themes

Added support for custom themes. You can now fully customize the look and feel of massCode — UI colors, editor syntax highlighting colors.

Themes are stored in ~/.massCode/themes/ as JSON files
Create a new theme directly from settings — a Rose Pine-based template will be generated
Both light and dark theme types are supported
Theme files are watched in real time — edit the JSON, see the result instantly
