If you are feeling adventurous, it is in fact possible to change the power icon without a code change.
the icon is in fact an svg in core parts and if you replace it it will look like this. Nothing seems to break, but that isn’t a guarantee something I haven’t seen yet doesn’t break. To make the change you need to download this svg (by right clicking on the image and selecting save image as, using power.svg as the file name)
and copy it into
which replaces the icon. The downside is that you have changed the core parts repository and automatic parts update won’t work any more ( keeping a copy of the original power.svg file and replacing it if you want to do a parts update will work though!) On Windows 10 (in use here) the full path is
Linux and the Mac are in different places I expect. I also didn’t change the icon file so Inspector still shows the old format even with the new svg loaded. Copying the same svg in to C:\Program Files\Fritzing\fritzing-parts\svg\core\icon\power.svg
should fix that (although I haven’t tested that!)
