How can I add tracks between specific pads programmatically in KiCad using Python?
Adding tracks between specific pads programmatically in KiCad can be done using Python scripting. The script provided demonstrates this by adding a track between pad #1 of footprint 'R1' and pad #1 of 'D1':

```python
import pcbnew
from pcbnew import wxPoint, wxPointMM

def add_track(start, end, layer=pcbnew.F_Cu):
    board = pcbnew.GetBoard()
    track = pcbnew.PCB_TRACK(board)
    track.SetStart(start)
    track.SetEnd(end)
    track.SetWidth(int(0.25 * 1e6))
    track.SetLayer(layer)
    board.Add(track)

board = pcbnew.GetBoard()
start = board.FindFootprintByReference('R1').FindPadByNumber('1').GetCenter()
end = board.FindFootprintByReference('D1').FindPadByNumber('1').GetCenter()
add_track(start, end)

pcbnew.Refresh()
```

This script provides a method for automatically adding tracks between designated pads, enhancing efficiency in PCB layout design.
