This extension lets you use different stroke colors to represent different laser powers (cut, engrave(heavy), engrave(light)).  Here's a video showing the use of the By Color presets option:

When using the By Color option the following stroke colors translate to the labeled actions:
{| cellspacing="0" cellpadding="5" border="1"
!Color
!Action
|-
|#000000
|Cut
|-
|#ff0000
|Cut
|-
|#0000ff
|Engrave (Heavy)
|-
|#00ffff
|Engrave (Light)
|}
'''NOTICE: When setting the hex values in Inkscape, the value is actually RGBA which has an alpha (opacity) value at the end so you will need to add an ff to the end of the values above.
