hi,
html & section picker is the fisrt thing I install right after a fresh WB install.
what is HTML modul?? ->code²?? if yes -> this is standard, too (i made several "admin comments" on the most pages where a editor have to use a modul like before a gallery section a shorthelp what to do or what don't....

section picker has replaced in my installations with the section picker droplet (it's more handy for templates and backend editors (droplet plugin in the fckeditor)
there are some other snippets that replaced with a droplet - like frontendedit, or loading jQuery Plugins too...
Standard is as well for me:
AFE
MPForm (only - if more than a simple contactform is needed)
Cutting all unneeded Icons in the FCKeditor (mostly two short rows left after that

)
foldergallery with some other lightbox themes (like fancybox if no slideshow needed...)
anynews (if news modul is good enought for the project - if not i use topics&anytopics like tutorials)
regards martin
