User reviews

Users find the 'ruler' add-on useful for measuring on screen but face several usability issues. The numbers are hard to read and often in inconvenient positions. The units of measurement are unclear. Users request more customization such as font size, hotkeys to toggle the ruler, and the ability to resize or move measurement shapes. These limitations lead some users to uninstall the extension in favor of alternatives.

Pros

Simple and useful functionality as a screen ruler for measuring elements.
Allows users to create rectangles/squares for measurement.
Generally works as intended for basic measuring tasks.

Cons

Lack of customization options such as font size and hotkey settings.
Difficulty seeing or reading measurement numbers clearly due to their size and placement.
Unclear units of measurement displayed (px, cm, inches not specified).
Inability to move or resize created rectangles after drawing.
No ability to easily turn off the tool with a shortcut like Esc key.

improve 1) hotkey setting; 2) description of what parameter D is; 3) turn it off with the Esc button; 4) reduce the font size.
