Inkscape

Visualize the order of subpaths within one path. Each start and end node will be marked with green/red dots and a text flag according to its order. Optionally the path ID could be visualized if working with more than one combined path.

I use this for various projects where combining paths is needed and the order is of importance - embroidery designs, developing and testing extensions for cutting/plotting.

This extension is based on the Inkscape included extension Visualize Path > Number Nodes by Aaron Spike from 2005. Number Subpaths can be found in the same menu when installed.

Tested for v1.01, v1.02 and v1.1 on Windows 10.
