I just noticed I erased my css changes on the core files by updating jve.
I thought it would be nice if it was possible to override JVE's output as it is a content plugin.
I saw that it would mean a tmpl folder in the plugin files of JVE docs.joomla.org/Layout_Overrides_in_Joom...erriding_a_Plugin.29
Well it's nothing important as I can put the css I use for jve in my template css.
It is just a suggestion
