Copying

• Cmd/Ctrl C copies the selected cell as real text plus one image per plot, instead of a single composite image. The text is a bold title (trial · tetrode · cell) followed by the spike count and peak rates, with no paragraph margins. It pastes cleanly into Word, Google Docs and PowerPoint.
• Holding Cmd/Ctrl C for a second opens copy mode. The hovered tile starts selected. Clicking tiles adds or removes them, and "Select all" (or Cmd/Ctrl A) selects every cell. The clipboard is rewritten after every change. Esc, Done or leaving the window ends it, and tiles outside the selection fade.
• Plots are captured off-screen (new WaveGPU.capture and a shared drawAnalysis), so cells scrolled out of view are included.

Tile-wall prompts

• Swap, split, merge (while dragging a tile) and copy share one instruction prompt above the tile wall. The split prompt replaces the old hint at the bottom of the screen.

Toolbar, focus and navigation

• Esc hides or shows the toolbar when nothing else uses it: an open split, swap, drag or copy mode, a focused panel, or the lasso. While it's hidden, a button at the top right brings it back.
• An unfocused window gets a vignette, so it's clear its keyboard shortcuts are inactive.
• The start screen is now a browser-history entry. The first recording opened is pushed after it, so Back returns home, asking first if cut edits are unexported.
• The toolbar's new Waveform icon returns to the start screen after a confirmation.

Visuals

• Narrower gap between waveform channels (about 2.5 px instead of about 20 px).
• Polished app icon (SVG), with favicon.ico regenerated from it.

Testing

• Lint, unit tests and the full Playwright suite pass.
• New e2e coverage: clipboard contents, copy mode (including cells out of view), blur ending copy mode, the Esc toolbar toggle, Back to the start screen, and home confirmation.
• The favicon test now checks both icon links.
