Library & navigation

Adding files

• Drag & drop — drop one file, many files, or a whole folder from Finder/Explorer. Loose files land in “Dropped files”; folders are walked (skipping node_modules, .git, dist, …).
• Open Folder — on desktop Chromium, pick a folder and Filemark shows the whole tree in the sidebar. The handle is remembered across reloads (a “Reconnect folder” button appears if Chrome ever drops it).
• Paste a URL — open a remote raw file; it's added to “Web docs”.

The sidebar

Collapsible (⌘B) and resizable (drag its edge). Sections:

• Starred — pinned files in a stable, muscle-memory order (star from the toolbar or a row's menu).
• Recent — the last files you opened. Clicking a recent does not reorder the list, so positions stay put.
• Web docs — the last 30 remote URLs you rendered, newest first, synced across tabs.
• Dropped files — loose files from drag-and-drop.
• Folders — one section per opened folder, with a file count, a per-folder filter, rescan, rename (label only), scoped search, and remove.

Each row has a menu: copy name, copy relative path, copy full path, star, remove. Folder collapse state and the sidebar width persist.

Tabs

Open multiple files as tabs; drag to reorder, click to switch, ]/[ to move between them, and 1–9 to jump. Each file remembers its scroll position across reloads, so you return exactly where you left off.

Full-text search

Press ⌘K for instant search across every loaded file, with query highlighting and the file's location shown. Type @folder-name to scope the search to one folder; the scope chip shows what's applied and Backspace clears it. Search state is remembered when you reopen the palette.

Table of contents & reveal

• TOC — toggle it (\) for a heading outline that tracks your scroll position; click to jump.
• Reveal in sidebar — the crosshair button expands the parent folders and flashes the active file so you can find it in a big tree.
