Version 4.5 will have the Keywords on its own page of a multi-page IPTC Info dialog.
I guess this didn't happen! I'm on 4.5.2 (Mac).
The new structured keywords feature is excellent and I'm tempted to use PM now for all major keywording, rather than iView (which is currently the part of my workflow where I keyword).
PM is still a bit clunky, though. The problem is that already applied keywords don't always seem to show up. If I click the 'i' icon for an image, then selected the structured keywords dialogue from the IPTC info dialogue, the keywords I choose are ten show straight away in the IPTC info box. But if I use the structured keywords dialogue directly from the main menu on a batch of images (my preferred method), the keywords don't show up in either the IPTC info dialogue or the keywords dialogue (it would be really useful to have already applied keywords show up in the latter).
When keywords are shown (as the previous poster mentioned) they're in too small a field.
I would really love to see a panel showing currently applied keywords (and perhaps selected other IPTC fields) in the contact sheet window, say below the navigation box. For multiple selections of images, it would be useful for this to show only those keywords they have in common (ie, that are applied to all selected pix).
