Hi,
I would also prefer the tooltip to be optional. For my work (mostly small and 
medium scale historical, physical and political maps) the tooltip is not really 
necessary. If I want to check the number of items in a layer I normally use the 
Crtl+A command. 
Regards,Andrei

 Going back to to differentiate Layerable

The list should be:
- Layer.class
a) layers which already have a datasource
b) layers with no datasource (layers in memory)
c) layers of type a) which have been modified and not saved
d) layers of type b) which have been modified and not saved

- RaferenceImage
no need for now to distinguish as we don't have referencedImage layer which are 
only in memory. It depends on what we want to do with this types of layer

-RasterImageLayer
Before Alberto modifications there was a problem as we used to have
a) Images with datasource
b) Images with no datasource (WarpImageToFence and ExportPartOfImge plugins). 
It was not a big problem as only two Pirols plugins were involved. Note that OJ 
still didn't have an option on "Closing Project/Program" that warn users if a 
"Sextante Raster Image Layer" was in memory or not.
After Alberto's modifications all Raster Layer are saved to OS/TEMP(*) folder 
so there is no need of that warning. So we only have option a)

(*) I am going to modify this and introduce an option to set a default output 
raster folder, like in GvSIG. And a unique ID to add to ouput temporary files 
(like in Kosmo) to prevent a) to loose files in TEMP folder if user is not 
aware and shut down the PC (expecially in Linux/MacOSX), b) to overwrite 
existing files with the same name (the actual used method LayerManager.class 
uniqueLayerName(String name) seems to have a problem with Raster layers loaded 
via Sextante)

common desktop software uses an asterisk after the file name eg. my_file.txt* 
to signal that this file has unsaved changes.

we could do the same after the layer name. .. ede
