None of the TinyMCE plugins have any user preference or database table. They all implement the null provider.
AMOS BEGIN MOV [common:browsemedia,editor_tinymce],[moodlemedia:browsemedia,tinymce_moodlemedia] MOV [common:browseimage,editor_tinymce],[moodleimage:browseimage,tinymce_moodleimage] AMOS END
We need to minimise TinyMCE tweaks, the advimage hacking was too big to maintain it during upstream imports, sorry.
