As I have gotten quite a few questions in the mail recently, regarding my tree widgets (Tree Table, Tree View and Matrix) which use a tree-like structure, I have decided to also publish the test-projects. As I don't want to pollute my current Github repositories, I have published them in a central repo now: https://github.com/JelteMX/widget-test-projects I will try to add more test-projects there. Currently I also added the File Dropper test-project. Let me know if you are missing any, I'll see if I can publish them as well. Do note that these test-projects ONLY apply to any widgets that I have released on my own Github (and have Community Support), not the ones that are published on the Mendix Github org.
