Support for REM Font Units and Increased Fluid Size Range

[faseehahmed1]

I am writing to propose a couple of enhancements that I believe would significantly improve the user experience and functionality of this already impressive product.

1. Support for REM Font Units: Currently, the left panel offers font size adjustments in px units. It would be highly beneficial if there was an option to change these font units to REM.

2. Expanded Fluid Size Range: The existing fluid size range of up to 5vw has been quite useful. However, extending this range to 10vw would offer greater versatility in responsive design, allowing for more dynamic scaling across different screen sizes.
