In the administration workspace, when editing a newly created profile, all the right checkboxes are checked by default, but if I don't save, the profile still has no right. I reckon this is to speed up the profile creation, as the user does not have to click on each checkbox, but this is disturbing: it seems we're editing a profile which already possesses all the rights.

In my opinion, two general 'check all/remove all' buttons (and maybe another 'check all/remove all' couple by category) would improve the general ergonomy of this screen.
