TinyMCE, the text editor we use for layout and styling, is extremely customizeable (for example, you can change what appears in the edit toolbar). A lot of that customization can be done in Wagn itself.
You can add
in the TinyMCE config, for instance like this
"theme_advanced_buttons1":"formatselect,bold,italic,separator,blockquote,bullist,numlist,hr,separator,code,outdent,indent"
