Common chord shapes

The shapes below were found by searching this tuning's fretboard. The search prefers the lowest playable position, requires every chord tone, spans no more than four frets and allows no muted string between two sounding ones. Shapes in an altered tuning are not the standard ones: they are the shapes this tuning actually produces.
