Hi all
I have begun to explore in more detail the editing capabilities of
GVSIG and would  state some remarks (or, better, some wishes) to the
point.
In detail, I think that the following improvements are needed:
1) I cannot select for editing purposes a feature af a layer from his
attribute table and features can be selected only on the geographic
display (the view) using the selection tools   available in the modify
toolbar (red arrow and blue arrow icons) or in the Geometry menu;
2) sometimes it is very difficulty  to select overlapping features one
at time. In these istances, the solution could be (like in AutoCAD) to
activate a cyclic selection using, for istance, the "ctrl" key;
3) creation of contiguous polygons: the only way for this purpose is
to digitize twice the sides common to the two contiguius polygons,
with the consequence of great time consuming and high probability to
run into topology errors. Solution: develope a new editing task like
"Auto-Complete Polygon" task in ArcGIS;
3 bis) should be needed other editing tasks like "split" (for lines)
or "cut"  (for polygons) features, "merge" two or more selected
features (using the attributes of one of them, choosen from user);
"clip" to create a hole in a polygon feature using another overlapping
polygon feature of the same layer (this is a frequently recurring
situation when I convert a dxf layer of parcels into a shapefile
layer)
...
etc.

 I realize that my wishes are easy to say, for me, since I am only a
user and not a developer, but I think that improvements in editing are
actually needed to transform GVSIG in a real alternative to some
commercial software;
Best regards and happy Easter
