The UI for merging tags can also be used to rename tags. As I understand it, it works something like this:
- There is a Master tag Textbox and a Remove/Rename Tag textbox.
- If the Remove/Rename Tag exists, it will be merged into the Master Tag.
- If the Remove/Rename Tag does not exist, the Master Tag will be renamed.
Wat.
These are two completely different functions--merging and renaming. They should be split within the UI because this dual behavior is not clear at all.
I would strongly suggest the two functions be split.
