Is it possible to have the option to color the layer with a gradient? Having linear, radial and mirrored gradient modes would be awesome! This would be useful for creating skies, colored filter ramps, colored vignettes and all sort of "theatrical" overlays and shading over the layers below.
I know that all this can be achieved with sprites, but using layers would be simpler object managing-wise, and the sprites would have to have high resolutions to avoid noticeable stepping value issues. The other option is R0J0s canvas Plugin, but, again, using layers would just be easier.
This is low priority of course, I just want to know if is feasible to go in the todo list
