🎨 Shadowforge Update – Layers, Timeline & Onion Skin Improvements

This update focuses on improving how layers, timeline interaction, and onion skin behave together. A lot of internal systems have been cleaned up to make the workflow more consistent and predictable.

🧱 Layer System Improvements

• Fixed issues where hidden layers (red eye off) would still appear on the canvas

• Multiple layers can now be hidden at the same time correctly

• Layer visibility now behaves consistently across:

  • Canvas rendering

  • Timeline

  • Onion skin

🎞️ Timeline & Layer Sync

• Timeline now properly syncs with the currently selected layer

• Selecting a layer from the right-side panel correctly updates the active frame surface

• Fixed cases where the timeline would not reflect the actual active layer

👁️ Onion Skin Overhaul

• Onion skin now uses the real layer surfaces (s4 → s18)

• Hidden layers are no longer shown in onion skin

• Onion skin now behaves consistently with layer visibility

🎚️ Onion Skin Opacity Slider

• Added a new opacity slider for onion skin

• Fully integrated with the Shadowforge UI style

• Panel is:

  • Draggable (like other FX panels)

  • Adjustable using right-click drag

  • Includes Reset and Close buttons

🧠 Internal Improvements

• Reduced conflicts between multiple draw/composite paths

• Improved consistency between:

  • Canvas rendering

  • Timeline surfaces

  • Layer visibility logic

• Better synchronization of:

  • current_frame

  • layershow

  • final_surf

⚠️ Notes

• This update focuses on stability and consistency rather than adding new tools

• Some systems (like timeline multi-selection) are still being refined

⭐ Thanks for testing and feedback—more improvements coming soon!
