What's your favorite custom normals editing workflow for modern Blender? I like the simplicity and native feel of built-in tools like "Mesh -> Normals -> Rotate", but it doesn't seem like those tools support customizing normals at the same vertex for different faces separately. I also tried "Perfectly Normal" addon and it's pretty good, but after applying its modifier it bakes normals into "custom_normal: Face Corner - Vector" attribute, while Blender's built-in tools and modifiers bake them into "custom_normal: Face Corner - 2D 16-Bit Integer Vector" attribute. And if you try to, for example, boolean union objects with normals in different formats, their normals will get split into multiple different attributes and the resulting mesh will get broken shading as a result. A workaround I found is data transferring normals from object edited with "Perfectly Normal" to a copy of itself with normals removed, which properly converts them to "2D 16-Bit Integer Vector", but it's quite annoying to jump between two formats if you want to use both built-in tools and addon, and it doesn't seem like addon supports all features of built-in tools to use addon exclusively (for example, you can't rotate normals around axis and you can't "Reset Vectors" - things you can with built-in tools). How are you doing it? Are there better plugins? Are there better workflows? Maybe I don't realize some features of built-in tools or addon in question?
