When I try to install the plug-in from the plug-in manager it just hangs on “Installing Pending” (see image below). I suspect that there may have been a change in KiCad 7 that broke the install.
I’ve also downloaded the plug-in manually by pressing the “Download” button on the Length Matching but I’m still trying to figure out how in use the manual downloaded file.
I have about 30 signals that go through a mess of parts that need the signal path to be the same length and I found this tool when I was starting to attempt to write my own.
