Overall it looks good, though I think the current layout is a bit messy:
Current Beta:
Mock up showing what I would prefer (but that’s just me):
Among changes:
- move Add another relationship under existing relationships
- invert position of delete / edit icons (like they are just above in this example)
- add a separator to ease reading
- I feel the ? icon isn’t needed, the entity could display it on rollover directly (for example, BBC Music ? could be replaced with just BBC Music, but still displays extra infos on rollover)
Just a quick feedback, the whole thing is quite an improvement already (finally only one Bandcamp URL)
Also, what’s the purpose of numbers? If they are here to stay, they should be first (from the left), as it is usual for numbered lines.
