Normally, i would not ask this feature in a "render" plugin's forum but over the years, corona introduced such niche features that i said why not!, this would save loads of time with many much like the UV Randomizer, Multimap, round edges and so on....
The shader i want to see corona team bring to life is a texture orientation shader, which would automatically rotate/orient the uv of a texture so that the longer edges of a polygon would define the orientation. This would be very useful as it would as it would be automatically useable on use it on roads , woodwork of the furniture, Ivy leaves etc... A polygon's UV would be automatically aligned along the longer edges
