Bette triplanar mapping

Hello everyone, as many of you might know already the box mapping in Blender shader editor can't be rotated without stretching the texture on one of the other sides of the box, however rotating the texture on the individual faces of the mapping box is a basic need for whoever works in architectural visualization, check the UVW map modifier in 3D max for example: youtube.com/watch

I've found an old thread on BlenderArtists talking about it here: blenderartists.org/t/impossible-rotate-a-texture-in-object-mapping/1129235/25

Someone found a solution with a very complex node group in the shader editor, this is partially what I needed, however I miss the "blend" of the original Blender box mapping.

It would be great if this Blender Artist's node group (which imitates the behaviour of the UVW map in 3D max) would be implemented in Blender too with the possibility to blend the edges of the mapped box.
