I wrote some jQuery to generate all the 'mw-ui-button mw-ui-big
mw-ui-constructive' button variations.
if you edit your User:<myname>/common.js and add to it
importScript( 'User:Spage/agoraPanel.js' );
then save and shift-Reload, then in the left-hand navigation area you
should see a button that inserts a whole mess of Agora buttons, and also
some checkboxes to load button CSS modules.
Let me know if you have problems and feel free to improve it. This isn't
to take away from the living style guide (now in core!), which will guide
people in using buttons well, it's just a tool to see them all when
