I believe your plugin has a lot of potential. In my particular case, I use relations all over the place and this is causing problems mentioned in the previous topic. I have tried getting the plugin to work now with several of my custom plugins and have run into either the Relation behavior problem (which I am still not sure how to work around), or an error such as:
[2019-06-28 15:39:48] prod-empower-app.ERROR: October\Rain\Exception\SystemException: The partial '_field_markdown.htm' is not found. in /home/joshm/shared/Sites/prod-empower/public/modules/system/traits/ViewMaker.php:91
I have gotten this for markdown, datepicker, fileupload, and relation. I am able to get past the error by touching a file in .../modules/backend/widgets/form/partials, but I am not sure what should be in there, and not sure yet how the frontend will render with just an empty partial because I end up getting stuck on the Relation Render problem.
