README.mdKiCad Swap Stubs plugin
this plugin swaps the electrical connection between two pins. It swaps the labels in the schematics and ratsnest in layout to keep the project in sync.
As plugin modifies schematic files it closes the schematic editor. The plugin creates a lot of whitespace changes in schematics file.
How to use:
- select the two pads on a footprint that you want to swap the electrical connection.
- run the plugin

Questions
What parts does the Swap stubs test project use?
2 parts, built around the 74LVC541AD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Swap stubs test project KiCad files?
From the MitjaNemec/SwapStubs repository on GitHub, at the commit this page was made from: the board is swap_stubs_test_project/swap_stubs_test_project.kicad_pcb and its schematic swap_stubs_test_project/swap_stubs_test_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Swap stubs test project design in my own project?
Its repository states no licence, so its author keeps all rights: ask MitjaNemec before reusing the design.
