Glance 0.2.0

Added

• Randomize button for all eight backdrop motions, with undoable, reproducible
  seeds shared by preview, PNG/GIF/MP4 exports and MCP, while retaining seamless loops.

• Reusable backdrop color popup with a color wheel, brightness, hex entry and
  image/screen eyedroppers; one solid color or two gradient/motion colors, with
  undo and matching PNG/GIF/MP4 output and MCP controls.

• Image Animation sidebar with diagonal reveal, spring pop, and 3D settle;
  independent backdrop motion, replay/scrubbing, and optional exits in MP4/GIF.

• Contextual sidebar options for all annotation tools, with separate defaults
  remembered during the session and undoable edits to selected annotations.

• Dashed and dotted lines, independent arrow/dot ends, editable waypoints,
  filled and rounded boxes, and reversible Raw/Smooth/Adaptive pen cleanup.

• Text sizing and opacity, highlight intensity, pixelation block size, crop
  aspect ratios, step numbers, spotlight dimming, and magnifier defaults.

Changed

• Removed the “New annotation” label from tool inspector headers.

• Tool shortcuts and brief instructions now appear in a hover tooltip on the
  help icon beside each tool's name, replacing the inspector footer hints.

• All tool inspectors use compact paired fields, editable numeric values, visual
  stroke/fill/endpoint choices and a shared custom color picker. Backdrop, Image
  tools and Animation use the same spacing and compact controls; annotation
  color sampling preserves opacity and is also available through MCP.

• Starfield is now called Nebula, with subtle evolving gas clouds, soft
  filaments and dark dust lanes behind the prominent drifting stars.

• Motion backdrop buttons have distinct small icons beside each effect name.

• Backdrop color controls use compact swatches, keep all eight presets on one
  row, and give Play/Pause an outline aligned with the duration slider.

• Lava backdrops flow through crossing currents, with stretching molten shapes
  and small globules that separate and rejoin the larger streams.

• Prism backdrops have irregular crystal facets, dimensional lighting and
  sweeping bands of refracted color, with subtler illuminated edges.

• Replaced backdrop canvas corners with inside padding that extends screenshot
  edge pixels, with matching image corners, shadows, preview and PNG/GIF/MP4 output.

• Linux release builds reuse optimized dependency libraries cached on main
  across release tags, alongside the existing CI test cache.

Fixed

• Capture and animation-export scratch files use private temporary directories,
  preventing local symlink attacks and exposure of unedited captures.

• Save dialogs preserve overwrite confirmation when checking filename extensions.

• MCP media reads reject remote URLs and special files; image imports enforce
  their size limit while reading, and Linux video decoding disables network protocols.

• Resized annotation widths and corners stay editable and round-trip through MCP;
  invalid transformed geometry is rejected before changing the image or undo history.

• Zero-length arrows retain their live stroke in exports, and incompatible backdrop
  durations return an action error before changing an image entrance.

• Text exports preserve glyph overhangs such as the left edge of “j”.

• MCP action discovery includes backdrop format and enable/disable controls;
  animation export descriptions reflect image entrances over still or absent backdrops.

• Translucent annotation exports preserve opaque image alpha and blend text
  and stroke joints consistently.
