I don't know if it's possible, but it would e really useful to be able to merge and split tags.
I love the possibility to automatically fetch metadata. But the problem is that I've ended up with 500 tags, which could be reduced to a couple dozen.
Merging:
I would select, for example, "fantasy", "fantasy epic", "fantasy & fiction", "fiction & fantasy", "adventure fantasy" into a single "fantasy" tag, for example.
Spliting:
I would select a tag and split it in two. For example: "fantasy & sci-fi" into "fantasy" and "sci-fi".
What do you think?
If it's already possible, sorry for being a fool. Please teach me how.
