I changed the widgets
"Defense Range Zero-K" and
"Show selected unit range" to have a thicker linewidth of 3 for defense ranges and selected units. 3 seems to be a good thickness for everything. I hereby publish those changed versions under the terms of
GNU GPL v2. The following linewidths are unaffected by this: Constructors' build ranges, range preview when placing buildings, missile ranges, lines that connect commands. The recent antinuke line width increase to 5 is considered.
Should I make PRs for such changes in the future? It just seemed to be faster this way and I wouldn't be sure if the PRs would be accepted.
To use a custom version of a default widget, do the following:
[Spoiler]Put its .lua file in the folder "Zero-K\LuaUI\Widgets". Start a battle. Deactivate the custom widget at the top of the widget menu, in this case "Defense Range Zero-K 2" or "Show selected unit range 2". Navigate to the default widget's options in the F10 menu, in this case "Settings/Interface/Defence and Cloak Ranges". Remember the settings there. Deactivate the default widget in the widget menu. Activate the custom widget at the top of the widget menu. Set your remembered settings in the custom widget's options in the F10 menu. Now you should have thicker lines with the same settings as before.
