I think the dolphin file-tagging widget shoulde be enhanced so that it can add several tags in *one* operation.
Currently, if you want to add a tags to a file, you have to click on the file, click on the tagcloud, create *one* new tag, name and describe it and restart the whole process over for each new tag. As I normally tag my data with 4 or 5 tags, this current workflow in dolphin is very cumbersome. I think firefox has a nice way of tagging bookmarks. It just uses a comma seperated list. You just type the list of tags, e.g. private, kde, 2009, bugzilla. If a tag does not exist yet, it gets created, otherwise the existing tag gets used. Perhaps a similar approach would work in dolphin?
