When creating an IPTC template the caption field is one tiny line. Please can this be expanded to several lines so that I can see the whole caption as I write it.
Also, Apple's Aperture used to show you the detail of the IPTC template in the import window before importing images, this allowed you to make slight adjustments to the template just for that import session. This would be very useful in Lightroom.
I might be wrong but I don't see any "Find and Replace" option for IPTC metadata. If I have an error in a caption or IPTC field I have to manually find and change each image instead of using a global 'Find & replace' string and choosing which fields it should apply to.
