That is one of the requests which came from the BoF session at the Plone 
conference. It looks like the ability to customise the buttons by 
permission or condition is a common request.

Right now, the way to do it is to edit the relevant .kupu files and insert 
tal:condition attributes on appropriate buttons. Then rebuild the widget 
template using 'make'.

I think a longer term solution will be to add another configlet tab which 
lists all of the buttons and lets you select an (optional) permission 
and/or condition for each one. Then change all the of the .kupu stuff to 
query the tool for each button.

I'm not sure when (or if) I can do that: the main problem is actually going 
to be hitting myself over the head enough until I can persuade myself that 
that is *all* the functionality which really needs to be added, and not the 
ability to drag/drop reorder the buttons in the configlet tab, add new 
buttons, edit the associated helptext, ...

Or of course someone else could always do it first.
