[victor-cds]

I use blender v2.93. I installed blender 3dmigoto addon.
a good addon. I imported the frame analysis file and exported raw buffer.
I have been useing this addon very well until I turned to search "Merge 3DMigoto Poses".
I pressed spacebar or F3 to search "Merge 3DMigoto Poses", I got no results found.
would you mind to tell me if there are any setting else?

I uploaded the add-on.

blender_3dmigoto.py

this is first few lins of the add-on.
#!/usr/bin/env python3
