View multiple PDFs side-by-side directly inside Logseq.

• Side-by-side PDFs — open any number of PDFs (up to a configurable limit) next to each other
• Two layouts — horizontal scroll or a dynamic grid (Übersicht)
• Click to open — left-clicking any PDF link in Logseq opens it in this viewer instead of Logseq's built-in PDF viewer; clicks add to the panel rather than replacing the current PDF
• Open from blocks — point at a block containing a PDF link and open it with one command
• Resizable panel — drag the left edge to change the viewer width; the size is remembered
• Theme-aware — picks up Logseq's current light/dark theme (and custom themes) automatically
• Page navigation — previous / next page per PDF

In Logseq: open the Marketplace (··· menu → Plugins → Marketplace tab) and search for Multi PDF Viewer. Click Install.

1. Download the latest release ZIP from the Releases page.
2. Extract it somewhere on your disk.
3. In Logseq: Settings → Plugins → Load unpacked plugin and select the extracted folder.

• Click any PDF link — left-clicking a [label](../assets/file.pdf) link in Logseq opens it directly in this viewer. Each click adds another PDF; existing ones stay open. (Ctrl/Cmd/Shift/Alt + click, middle-click and external http(s):// PDFs are left to Logseq's default behavior.)
• Toolbar button — click the 📄 icon in the Logseq toolbar to open the viewer.
• Command palette:
  • PDF Viewer öffnen — opens the empty viewer panel.
  • PDF aus Block im Viewer öffnen — reads the currently selected block, finds a Markdown PDF link like [label](../assets/file.pdf) and opens it in the viewer.
• Inside the viewer:
  • + PDF — same as the block command above.
  • ▦ Nebeneinander / ▤ Übersicht — switch between layouts.
  • Drag the left edge of the panel to resize.

• Maximale Anzahl PDFs (maxViewer, default: 4) — how many PDFs can be open at once. When the limit is reached, the oldest PDF rotates out.

npm install          # install dependencies
npm run dev          # start Vite dev server (port 3000)
npm run build        # build for production (output: dist/)

After each build, reload the plugin in Logseq (Plugins → reload).

• React 18 + Vite
• PDF.js (legacy build — required for Logseq's Electron runtime)
• Logseq Plugin API
