I recently added HtmlEditorConfig::get('cms')->enablePlugins('safari'); to my _config.php file to get some Safari bugs out of TinyMCE. I plan on using it on all future projects.
Wouldn't it be a good idea to have this line in all stock SilverStripe downloads. I think it would help a lot of people that might not find the documentation. Or is there a problem that I'm overlooking there.
I think in the latest TinyMCE builds they have added the safari fixes back into the main release. Theres a ticket on open to upgrade TinyMCE to this latest version but not sure when this work will happen.
