Please consider to add an item to the filter list:
- Show images with keywords
Removing the check from this item would filter out all images that have already been keyworded. A second item, “Show images without keywords” could also be added to allow the user to have more specific control.
This is ideal: Suppose the check has been removed, so that only non-keyworded images are selected. When a keyword is added to the active image (or several keywords separated by commas), that image would be removed from the list of active images, the display would advance to next non-keyworded image, and the cursor would remain active in the keyword text box. That way, a user could quickly add keywords to all images one at a time.
