v1.0.4

Add align/arrange, snapping, rulers & guides, eyedropper, nudge, preview opacity

• Z-order: Bring to Front/Forward, Send Backward/to Back (Ctrl+] / Ctrl+[ and
  the Shift variants), in the Edit menu and right-click Arrange submenu.
• Align & Distribute: align the selection by edges/centres and distribute
  spacing; each object or group moves as a unit.
• Arrow-key nudge (1px, Shift = 10px).
• Smart snapping while dragging: snaps to other objects' edges, centres and
  transformed corners, and to guides, with a magenta indicator; Ctrl bypasses.
• Rulers (Ctrl+R) with drag-out horizontal/vertical guide lines; drag a guide
  onto a ruler to delete, or Options > Clear Guides. Editor-only, never exported.
• Eyedropper (I, plus buttons in the Color and Properties panels) with an
  eyedropper cursor; click an object to apply its colour to the selection.
• Preview opacity (right-click): a visual-only dim that never changes the
  exported colour; dimming a group flattens it so overlaps don't compound.
• Marquee selecting any part of a grouped object now selects the whole group.
• Fix the Color panel RGB sliders (they read the spin boxes instead of the
  slider positions, so dragging did nothing).

v1.0.3

Editing & Workflow Update

Isolation Mode (new)

• Double-click a group to enter isolation — edit only that group's objects while everything else stays visible but
  subdued.
• Inside a group, objects select individually (no need to ungroup to edit them).
• The backdrop behind the group is uniformly dimmed as one flattened image; layers stacked above the group are hidden
  so the group is clearly on top.
• Double-click deeper to step into nested sub-groups; Esc (or double-click empty space) steps back out one level.

Grouping

• Group and Ungroup are now separate actions. Ctrl+G groups only (never ungroups); Ungroup has no shortcut.
• Grouping no longer requires objects to be adjacent in the layer stack — any 2+ shapes sharing a parent can be
  grouped and are gathered together.

Right-click canvas menu (new)

• Group, Ungroup, Flip Horizontal/Vertical, Rotate 90 CW/CCW, Lock Selection, Unlock All.

Transform

• Flip now performs a true mirror instead of a 180° rotation (an unrotated shape stays at rotation 0).
• Rotate 90° CW/CCW rotates the selection rigidly about its center.

Selection & moving

• Dragging a multi-selection moves all selected objects together instead of collapsing to the one you clicked.
• A selected object stays draggable even when another object overlaps on top of it.
• Locked objects are no longer selectable on the canvas — clicks pass through to what's above/below (respects group
  locks).
• The transform box hides while you drag to move and reappears on release (Illustrator-style).

New shortcuts

• Ctrl+J — Duplicate
• Ctrl+2 — Lock Selection
• Ctrl+3 — Unlock All

Fixes

• Paste now always lands in front of the original (previously could paste to the very back on ungrouped projects).

v1.0.2

Add Illustrator-style Color panel and refine the panel/selection UX

• New dockable Color panel: recent colours, R/G/B sliders with live
  gradient tracks, hex field, and a hue/value spectrum. Double-clicking the
  fill swatch (or a recent colour) opens the colour picker. Edits apply live
  to the selection as a single undo step and stay in sync with Properties.
• Right-side panels are separate stacked sections (Properties, Color,
  Project/Header) with a thin 1px divider only between stacked panels. They
  are scrollable and size to their content so each opens fully; heights are
  re-applied on maximize so nothing is clipped or overlapped.
• Shapes browser tiles are flat: no per-tile box/outline, hover fill only.
• Locked objects are no longer selectable on the canvas - click, marquee and
  hover all skip them (respecting group locks) so you can grab what is above.
• Dragging a selection to move it hides the transform box until release,
  matching Illustrator.
