This plugin primarily adds a customizable scratchpad layer during Anki reviews, allowing users to freely draw, write, or even input text, eliminating the need for paper-based calculations or scribbling. Key features include:
• Customizable Scratchpad: When a review session begins, a scratchpad layer is automatically created on the review interface, enabling both handwriting and text input.
• Offers various control buttons, such as clear scratchpad, close scratchpad, color selection, thickness adjustment, and mode switching.
• Supports switching between handwriting mode (for drawing) and text mode (for text input).
• Display Only During Reviews: The scratchpad is only visible during review sessions, and its control buttons dynamically adjust their position and size when the interface is resized.
• Automatic Clearing: After completing a card review, the scratchpad content is automatically cleared, and a new scratchpad is created when the next card review begins.
