Hi @Pyroh and great work on this tool!
Please note that both in the README and the files within the projects, it is unclear what License you released the code in. Since you're talking about integrating xspmkit
to a GUI app as an example, I suppose you meant to make this open source. MIT would be a widely used license I can recommend for this tool. But in any case, no one can really use this tool anywhere or contribute to it, when the License isn't clear (and therefore everything is automatically copyrighted).
