I remember a function, that was available in version 5, where the shown icon is located.
With activated icon I could select any copper line in the layout and the whole net was highlighted.
This is something I’m missing in version 6.0.5 (and before).
I checked the documentation for net highlighting and found out, that the context menu is available and operating properly. The key shortcut isn’t working well, I have to redefine the selecting key to make this feature working, the default key " `" and " ~ " isn’t working. (maybe because of german version/localization/keyboard?)
As already said, nothing is happening when selecting the icon or with selected icon.
For curiosity, what are the context menu entries “hide net” and “show net” for? I see no effect in the layout.
It would be nice to get the icon operating again.
