hi Gael,

I might even agree more with you than you or I thought at first sight ...

very good point, should be done all the time !

it's boring, but also a very good point,
although I'm not a MS fan at all,
all programs should be good as Excel at this point.

I'll hope the future will change that: simple programming for everyone !

agreed.

More than agree,
my adagiao:  "the best programs are written by users",
unfortunately programming is yet too difficult for most domain experts.

And now I get a strange feeling, ...
... that I'm working on some kind of traits,
maybe a lot less sophisticated,
but on the other hand much easier ;-)
thanks for the explanation,
cheers,
Stef
