This extension was part of Blender 4.1 bundled add-ons. It is now offered as it is, with limited support.
No changelog for this release.
This extension does not require special permissions.
I'm going to give it a FULL rating because I know exactly what this can do for me and its overall potential.. However...
It appears to be broken, at least for me, using blender 4.2.2LTS on linux.
The basis of the problem is pathing. everything I do is 100% relative and so the extension reports the .blend asset file as //../../../../Assets/chairs.blend .. but when I load the blendfile through this addon it gives me an empty blender project named '/Assets/chairs.blend' <-- completely blew off the path
I decided to give this plugin a try after reading the reviews, and I’m glad I did! It’s a huge time saver and works seamlessly. One of the standout features is the ability to open a new Blender instance while keeping your current session running, which is incredibly useful. Tested and working perfectly on Blender 4.3.2. Highly recommend!
