Roadmap

Suggested improvements, drawn from the comparison with other tools, the research and testing. Ordered by how much each would help against how much it costs. Every item has a ticket on the board.

Done: make the editor feel like an editor

The tracer was ahead of the field and the editor was the gap. These shipped together; see Editing shapes and Keyboard shortcuts.

Item	What shipped	Ticket
Scale and move shapes	A Select tool with a bounding box: drag to move (⇧ one axis), square handles to scale (⇧ in proportion, ⌥ from the centre), typed X/Y/W/H, arrow nudges.	#21
Drag to select	A marquee for shapes (wholly inside) and, with the Nodes tool, nodes. ⇧ adds, ⌥ removes; ⇧-click toggles; several nodes drag together.	#22
Smooth nodes	Dragging one handle of a smooth node swings its partner round to stay in line. ⌥ breaks the pair; corners stay independent.	#23
Shortcuts and a shortcuts panel	V, A, M for tools, arrows to nudge, ⌘A, and a panel on `?`.	#24
Fix the Smoothing “Off” label	Flat-art presets show the tolerance (±0.25 px at the bottom); Poster keeps “Off”, which is true there.	#26

Done: close the gaps with the paid tools

See Editing shapes, Colours and background and Export.

Item	What shipped	Ticket
Add node, convert node	Double-click the outline to add a node (the curve is split exactly); Smooth and Sharpen on the selected nodes.	#27
Merge colours	Merge on a colour re-traces with one fewer, so the edge between them goes; Unmerge takes it back. Logo and Illustration.	#28
Eyedropper	A pipette on every colour and the background picks from the original image; Pick from screen in Chrome and Edge.	#29
Corner sharpen and round	Sharpen drops a node’s handles; Round corner replaces a corner with an arc of a chosen radius.	#30
Simplify selection	Re-fits the selected shapes with the tracer’s own fitter at a chosen tolerance, showing the node count first, and never collapses a thin shape.	#31
Rotate	A handle above the box (⇧ snaps to 15°), quarter turns, or a typed angle.	#32
Export size and PNG	Width and height in px, mm, in or pt for every export; PNG at 1–4× or 72–600 dpi.	#33
PDF and EPS export	Built in the browser as real vector paths, one page at the export size.	#34
Session save	Image, settings and edits kept in this browser’s IndexedDB; Start over clears them.	#35

Next: bigger bets

Item	Why	Ticket
Symmetry detection	Find mirror and rotational symmetry in the trace and enforce it, as Vectorizer.ai does. The manual mirror covers the common case.	#36
Shape fitting	Recognise circles, ellipses, rounded rectangles and regular polygons and write them as exact shapes.	#37
Centerline tracing	Single strokes for plotters, engraving and handwriting, rather than outlines.	#38
Background removal and upscaling	In-browser models for photos and low-res logos, held to the licence rule (MIT/BSD/Apache weights only).	#39
Target file size	“Make it under 10 KB”: search the settings for the best trace that fits.	#40
Groups and layer reordering	Treat several shapes as one; move a shape above or below another.	#41
DXF export	For CNC and laser cutting.	#42
SVG import	Open an SVG to edit its paths, so the editor is useful on its own.	#43
Batch	Trace a folder of images with one preset, download a zip.	#44
Offline install	A service worker and manifest so it installs as an app and works offline (SVGcode does this).	#45
HD mode	A paid, server-side trace for very large images: a Vercel Function with spend caps, opt-in, clearly marked as leaving the device. No database.	#46

Not planned

Uploading images by default. Local is the point; HD mode would be opt-in.
GPL/AGPL code (Potrace, AutoTrace, @imgly/*). The repo is MIT.
A general vector editor. Edits exist to fix traces; Figma and Illustrator are better at everything else, and Copy SVG gets you there.
