It would be great to be able to set the REM value per frame/section too.
If the default REM is set to 16 px it would be great to be able to side-step that for a section that is mobile frames for example.
One option could be to be able to change the REM value at the code settings, and change the value.
It would also be a great feature if the variables would be possible to add math functions. For example that a [variableA] = 3*[variableB].
I know there are plug-ins for that but if that would be part of the basic FIGMA feature regarding variables.
