now I think I understand what do you mean. I just noticed that in QGIS
master the towgs parameters of CRSs in use for Portugal have vanished.
Is on purpose or should I consider it a bug?

for example in QGIS there are both the epsg 20790 that had the
parameters and its counter part without (102164) and the user was able
to choose between the two, choosing if he wanted the shift of not.

If the parameters removal was on purpose (also for other CRSs for
other countries) then we can have a serious issue.

Also I have personally a lot of difficulties understand how the datum
shift dialog works, then I guess that most of the people will have the
same problem :)

ntv2 grids were also added to the datum shift database, but never
managed to have them show in the dialog. What I'm doing wrong?
