Choose View > Show Grid Command+' to overlay a drawing grid. Use View > Grid Size for the drawing lattice (1×1 is the pixel grid) and View > Tile Size for a coarser tile interval (Off, or 8×8 up to 128×128). Tile boundaries draw as a thin see-through gap rather than a line, so each tile reads as a separate island while you draw freely across them. The tile grid is always at least as coarse as the grid. Choose Other Grid Size… to type custom widths and heights for the open document.
A cell appears once it is at least 8 points wide on screen, so an 8×8 tile grid is already visible at 100% zoom, while the 1-pixel grid waits until 8×. Style—Gridlines, Centre Dots, Corner Dots, and Crosshairs—and opacity (25%–100%) apply to the grid only (tile gaps are style-independent) and are in the View menu. Line width (0.5–4 px) and the default sizes for new documents are in Settings > Grid.
Looking for the retro scanline look? That's now a separate display filter, not a grid style—see Settings > Display to apply a CRT effect to the canvas and/or previews.
Inspector: Window > Show Inspector Shift+Command+L toggles the right-hand panel with layers, animation, and preview sections.
Sidebar preview: Window > Show Preview Shift+Command+P shows a live actual-size preview in the inspector.
Floating preview: Window > New Preview Window Option+Command+P opens a preview that floats above every window—keep your sprite at 1× in the corner of your eye while you work zoomed in.
Choose Window > Coordinates Option+Command+K to open a small floating readout in the style of classic Mac coordinate palettes. Its four cells update live as you work:
| Cell | Shows |
|---|---|
| X / Y | The pixel under the cursor—including while you're drawing. |
| W / H | The width and height of the current drag. |
| X / Y (start) | The pixel where the drag started. |
| Angle / Distance | The angle in degrees and length in pixels from start to cursor. |
The drag readouts work for any drag—drawing, selecting, or moving—and hold their values after you release, so you can read the slope and length of the line you just drew. Click the green zoom button to collapse the panel to just the cursor and size row, and again to expand it. The panel never steals focus from the canvas, follows whichever document is frontmost, and reopens at launch if it was showing when you quit.
