Hi Fab1en, Joost
I too would love this feature - specifically for custom taxonomies too. I have just had a nasty experience when one of my team tried to code noindex into a theme header for a product tag (custom-tax) it went wrong, wasn't tested properly, now site had lost 99% of search traffic :( Problem is fixed and hoping a recovery won#t take too long. Having this an option in the indexation section would be awesome - I'd buy you a Beer!
OK, in fact I just checked and seen you have v 1.2.3 out. Installed and changing 'tabs' to taxonomies does nothing... clicking any tab just changes the URL (..site/wp-admin/admin.php?page=wpseo_titles#top#taxonomies) but content of screen doesn't change... (still WP 3.3.2) does it require WP 3.4.1?
