Hi Mohammed,

To toggle visibility of a Sextante Raster Layer, you have to right click on the layer and change its visibility from the context menu. I don't know why it has been done like this. May be to make them different from old Raster Layers.
If someone else know, it would be interesting to discuss this choice.
My opinion is that it would be better to have a common way to toggle visibility for all layers including Sextante Raster Layers.

About getting cell values, I think a useful plugin would be to display cell values of the topmost visible raster layer in the leftmost part of the status bar when the info button is on.
What other users think ?

My 2 cents

Michaël

        What do you mean when you say the layer isn't "checkable"? You
        mean
        you can't toggle its visibility?
