Thank you so much for the kind words and the review!
Regarding the pivot rotation on inclined edges: by default, the pivot's orientation is aligned to the surface normal, which is why it can look tilted on sloped geometry. This is intended, but you're not locked into it — you can freely re-orient the pivot yourself:
Hope that helps solve your issue! Let me know if the rotation still behaves unexpectedly.
Thank you. This is a very good plugin. It makes the modeling process much more convenient. But I found that when the pivot was placed on some inclined edges, the rotation of the pivot would be incorrect.
