Artboards Panel Preview Enhancement

Add a thumbnail preview inside the Artboards panel, similar to PowerPoint slides, so designers can quickly identify each artboard visually without navigating back and forth on the canvas.

This would help designers:

• Quickly know where they are
• Spot missing or unfinished artboards
• Export the correct artboard faster
• Review layout consistency at a glance
• Save time in multi-artboard projects

Please add visual thumbnails/previews to the Artboards panel, similar to PowerPoint slides, so designers can quickly identify, review, and export artboards without constantly navigating across the canvas.
