I mostly use the source editor over the visual editor, but use the latter for referencing and I use ProveIt for citations, as I'm not too good at using the templates.
Do you know the CC BY-SA/GFDL License inside-out, and have thousands of edits to your credit? Are all those copyright disclaimer warnings starting to bug you? Add this to your (pick one): vector.css (default), monobook.css, modern.css, minerva.css Skin (or add it to your common.css to hit all your skins):
/* Remove to-me-useless notes in all edit boxes. leaves only the command buttons and special chars. */
#editpage-copywarn { display: none; }
#editpage-copywarn1 { display: none; }
#editpage-copywarn2 { display: none; }
#editpage-copywarn3 { display: none; }
div.editpage-head-copywarn { display: none; }
