Right-click blocks in the graph, Document tree, or Libraries tree and choose “Port Options…”.
Unified port list with:Add/remove port
Name
Type (Signal currently)
Input/output orientation
New ports start at (0, 0) in the icon editor.
Connected ports cannot be removed, reoriented, or changed incompatibly.
Added a PortType registry; connections require matching port types.
Removed/hid the separate Add Input and Add Output workspace tools.
Library port changes are written back to the library JSON.
Added independent graph and icon grid-size settings.
Components, interface terminals, icon shapes, resize handles, and icon ports snap to their corresponding grid.
Icon canvases and component hitboxes are now fixed at 128×128.
Selected icon shapes show a bottom-right resize handle.
Circles preserve equal width and height while resizing.
Shapes and ports are constrained to the icon hitbox.
Fixed the icon-editor crash and grid behavior.
Renamed the resize handle’s shape attribute, which was overriding Qt’s required shape() method.
Icon shapes, resize handles, and port anchors now snap while dragging.
Graph blocks and interface terminals also snap while dragging.
Replaced the nearly invisible dotted graph grid with higher-contrast grid lines.
Retained final release-time snapping as a safety check.
Python compilation and diff validation pass.
Key changes:
Component Options now has an “Edit Icon…” button instead of direct shape/color fields.
Icon editor supports:Rectangles with configurable corner radius
Circles and ellipses
Lines
Triangles
Text
Movable/selectable shapes
Shape context menus
Line style and width
Solid or transparent fill
Stroke and fill colours through Qt’s colour picker
Editable shape dimensions
Deleting selected shapes
Input anchors are green and output anchors red; both can be dragged around the icon.
Icons use a 120×80 vector coordinate system and are stored as editable elements in document JSON.
Components render their vector icons directly in the workspace.
Library and document trees display 16×16 icon previews.
Added a Camera toolbar:Zoom In
Zoom Out
Center
Mouse-wheel zoom works directly over the workspace.
Icon changes and port positions support undo/redo.
