As comprehensive as the last chapter was, it didn’t cover everything there is to know about paths in Inkscape. This chapter is smaller, but it has the potential to grow much larger in later editions as Inkscape continues to evolve. Path effects (13.1 Path Effects) first appeared in version 0.46; they are really taking off in version 0.47 and will likely grow even more in future versions. Extensions dealing with paths (13.3 Path Extensions) are another area of continuing growth; in the future, some of them may be turned into path effects to improve interactivity and integration with the rest of the program.
