The Magnifier software is a cursor-linked tool that can be replaced with a magnifier in settings. It's ideal for pixel editing in graphics editors and easy for inspecting small details.

This tool has proven to be quite useful when editing pixels or examining small details. It certainly saves a lot of time and effort when trying to perfect an image.
One thing I appreciated about using Magical Glass is how easy it was to navigate. While it's running, a Magical Glass icon is displayed in the system tray, located at the end of the task-bar. It's always there when you need it, and it doesn't take up valuable screen space.
Overall, if you're a graphic editor, I highly recommend giving Magical Glass a try. Its magnifier feature alone is worth it, and it's incredibly convenient to use.
