great!
Why this hasn't been purchased by blender for a huge amount of money is beyond me. this should be included in blender by default. The dev of this got this right. ive never in my few months of using this have had a single issue with it. its one of the most useful plugins you didnt know you needed.
Works perfectly. Should be built-in.
Only comment I have is that it uses the same icon as the popular Photographer add-on, and they are right next to each other, causing confusion. Maybe consider just the LINKED and UNLINKED icons? Also, maybe an option to just not show the button at all?
