Copy-paste of portals (complete with fields) and than (possibility to)change the relation, would be VERY nice! (like in Filemaker) Copy-paste to another form would be nice too!
for example: I am building an order system with a portal full of line-items,
and a portal full of products (like in CRM demo) after a few hours af work, to get all things right, I came to the conclusion that I had too much information on one screen, so that I want to split up information to Tabpanels (with a self-join!) Now I have to start all over again, because I can't copy-paste the portals with all the fields to another form.
