UV Snapper - Blender Addon

*Now available as a Blender Extension from within the program itself! (https://extensions.blender.org/add-ons/uv-snapper/)
Just search for "UV Snapper" in the "Get Extensions" tab.*

UV Snapper (https://github.com/Falking3/UV-Snapper) is a Blender addon designed to speed up atlas or trim sheet based workflows, best paired alongside Dream UV (https://github.com/leukbaars/DreamUV). When using DreamUV I found that some shell shapes would not unwrap well, resulting in me having to straighten them and manually position them so that the edges lined up with the box. This was designed to solve that problem.
I've been working on this for a long time and have rewritten it from top to bottom several times as my python and Blender knowledge has improved. Any and all feedback is greatly appreciated.
