1️⃣ Describe the feature
By default, ImageGlass zooms into the center of the image. For infographics or very tall, script-generated diagrams, this requires a tedious two-step process:
- zoom in,
- then pan to the actual section you want to see.
Proposed Feature:
Allow zooming relative to the mouse cursor position (e.g., by holding Ctrl while scrolling).
The view should center on the cursor arrow as you zoom in or out, acting like a magnifying glass.
This would make navigating large images much faster and more intuitive.
2️⃣ How to use feature
- Ctrl + Scrolling
you would get zooming at the point of the cursor.
release the ctrl, and scrolling would zoom from the center -- like it currently does.
3️⃣ Additional context

Research direction
The issue names no files, tests, or entry points. Start by locating ImageGlass's current center-based scroll-zoom handling and the input path for Ctrl plus mouse-wheel events. Done means Ctrl-scrolling zooms around the cursor while ordinary scrolling retains the current center-based behavior.
