Increase visibility of fixed sketch element

[kjellhar]

In the sketch enviroment, fixing an element will change its color to green. This can very difficult to distinguish from black lines against a grey or brown backgound the line is very thin, and it's a darkish green.

So, my suggestion, which technically should be a quick fix, is:

 -  Use a more bright green

 -  Add some weight to the line, making it maybe twice as thick or something.

Optionally you could add a symbol like you use for the other constraints, but that will even further clutter the sketches.

We've made some improvements to the sketch environment by changing some line colors for better visibility. Can you try it and let us know if it fits your needs?

That looked much better. The change from bright blue to green was much more obvious.

Thanks,
