Hello there and PeterC,
Fedora Electronic Lab includes too many EDA software and the actual
electronics-menu drowns the user into confusion. I have created
submenus on electronics-menu as you can see on this screenshot:
The idea is that the packager added the category "Electronics" to the
desktop file and hence the electronics-menu automatically shift it to
its appropriate submenu.
Below are 2 patches and the additional sources, they have been tuned
so that they are distribution independent.
I am currently pushing it to the fedora testing repositories. Tomorrow, you can
yum update electronics-menu --enablerepo=updates-testing
Else you can pull it from here
Happy testing and I hope other distributions will adopt it as well.
