Currently the import of a map will populate many shelves including: decals, materials, alphas, stencils, textures and environment maps. It seems very messy to have this be the default action especially since it seems difficult to remove an image? I would like to see explicit imports of images to specific shelves. Also a remove map function would keep things cleaner.

note: MARI has a nice feature where images can be dragged in from viewers including web browsers right into the image manager. Very intuitive.

I typically paint a project with up to 50 meshes. The ability to have a mesh selector like material eye-dropper would be awesome. Click the mesh selector button and whatever mesh you click on next becomes active.

Lots of material presets are meant to be scaled along X and Y uniformly, and it would be convenient if there were a toggle that allowed both numbers to change after setting only one value or dragging one slider.

Also I could not overpaint imported texture inside painter. Is there any way to edit them?

I don't know if this in already planned, but when I import images, alphas, etc. currently, the images are all over the place. What if during the import process, it will ask us where we want the image to go... would save us a huge headache looking for it.

It would be nice if we could rearrange the Shelf sub-windows like regular windows, or toggle between horizontal and vertical orientation.

Here is an example of where the current system fails: This is my setup: https://dl.dropboxusercontent.com/s/iwnhurq9fxjkn5s/shot141105103455.png?dl=0 (squashed tab bars).

Base Color, Height, Roughness, Metallic, Specular, Glossiness, Reflection, Displacement (maybe as bump) all these things in one shader.

These things are very important in the production.
additionally, it would still be nice if you could see displacement. I know Displacement goes heavy on the graphics card, but even as a bump map to see it, would be great. You can combine it with the height, but the possibility to have displacement would be great.

If i Decied, turn painted BaseColor layer to a Height or Metalic...
sory about my engl :)
