I have implemented a couple TinyMCE plugins in Plone but it's not clear to me what exactly you are asking.
There should be roughly two steps you need to do:
Have the plugin js available as a browser resource somewhere e.g. "++resource++my.package/plugin.js". I would not try to compile/merge it with the regular resources in plone-logged-in as TinyMCE will want it as a distinct resource
Register it as a custom plugin with the plone registry, either with GenericSetup or through Plone in @@tinymce-controlpanel -> Plugins and Toolbar -> Custom plugins. Assuming the resource URL in #1, this would be something like "myplugin|++resource++my.package/plugin.js"
Hi, thanks in advance.
I have a question. You have tried to add an extra plugin for tinymce and integrate it into Products.CMFPlone, that is my main target and it would also help me to know better how Plone works.
I really want to collaborate more with the community.
