This is not a new userscripts but it’s my NUMBER ONE USERSCRIPT (of the universe).
I have only just made a first wiki post for tracking discussions and updates about it.
mb. COLLECTION HIGHLIGHTER
This script shows you what release or recordings (among other MB entities) you already have in your collection(s) or are in other people’s collections, because there is no restriction on user.
Here I can see the albums I have, they have that purple highlight.
The non-highlighted albums, I don’t have them, yet.
Here I can see that in this vinyl edition, there is a bonus truck that I don’t have.
My CD edition does not have this acoustic version, it is not highlighted.
Because all recordings I have will be highlighted everywhere in MB, where they appear.
Same for works, artists, releases, release groups, etc.
Yes. it is BERY POWERFUL.
It’s the reason why I use MB.
It works on Firefox for Android 68, so I can check if I should buy this or that CD / compilation / special edition, when I am at flee market or second hand CD shop.
It should really be in MusicBrainz code itself, in my opinion:
Please all discussion about mb. COLLECTION HIGHLIGHTER should go to its now dedicated topic, below.
