Thanks for responding. Sorry, I probably should have gave an example of what I needed to do.
I am migrating a U7 client to U10, and on their U7 instance they use the "templates" option for inserting some content into RTEs. That is the main thing I wish to replicate, or identify alternatives if its not possible. Beyond that, I was wanting to look into adding some plugins that could improve the editing experience. Search and replace, quick bars and maybe some others depending.
