@idefix37 Thanks, it is pretty standard color code of many weather routing services. Please see the codes below:
[[0,[200,247,249,256]],
[1,[155,222,237,256]],
[3,[125,219,233,256]],

@marekd Appreciate your suggestion, indeed saving URL is working. Hopefully the feature would be added in the future.
Your website is very helpful for us seamen as well, good job!

Good day Sirs,
Would like to ask how to "activate" saved route, once it is downloaded from the file I saved earlier. The thing is, when you create a new route, it is active and by moving pointer on the time bar, the position of the "boat" is moving with the time and speed you specify at the bottom.!
However, when I load the saved route, there is no way to "activate" it again to be able to see the prognosis again and to move the "boat" with the speed you specified earlier, so basically you are able to see the route you saved earlier, but details are not active.
Thus the question - is there a way to activate all the data once again, when the route is loaded from the saved file?
