[Feature request] Sketcher styling parameters

[pablogil]

Hi,

I've been playing today with custom sketcher colors and I like it (I always love to be able to customize GUIs to my preferences), anyway I miss some parameters that seem not to be able to be customized:

• lines width
• datum arrow color
• datum style (option to switch between arrow, dot and none)
• datum line width
• grid color
• grid line width

Would it be easy to include?
Thanks!
