It’s a minor thing I’ve noticed. Compare the tag auto-completion of DT3 with that of the standard tagging via e.g. the Finder. If the tag
paper already exists and I’m typing
Paper, the tag is recognized as belonging to
paper thus avoiding unwanted duplicates. As for DT, I have several variants of tags either capitalized in the beginning or not. This regularly requires me to manually reassign tags and delete the duplicates – until I’ve gathered another set of falsely tagged documents.
Having this (perhaps just optionally if it’s not a common concern) would be neat!
