The Scratch Highlight Fullwidth Number Chrome extension is designed to enhance your Scratch coding experience by automatically detecting fullwidth (全角) numbers, which are a common source of bugs in Scratch projects. When such fullwidth numbers are identified in your Scratch code, the extension highlights them in red, making it easier for users to spot and correct potential issues promptly.

This simple yet effective tool helps prevent coding errors related to character format, streamlining the debugging process and improving overall project stability. It is especially useful for Scratch users who might accidentally use fullwidth numerals due to their input settings or keyboard layout.

By integrating this extension into your browser, you ensure better code quality and reduce the time spent on troubleshooting numeric input errors in Scratch projects.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Scratch Highlight Fullwidth Number requires very minimum permissions.
