Wouldn't it be absolutely *neat* if we could put together our own menus,
I'm not sure: too much customization kills customization :) see emacs, ms word's toolbars... However, language modes could change such defaults and set some commands (eg. group 'build C file' 'build Java class' 'pdfLaTeX this file' and such as a single 'Build this file as the mode says to', with only one keybinding)
