Hi Gonzalo,
FWIW, I've never been able to get along with the default behaviour of
Fl_Pack, so tend to go with something like Greg's suggestions of
putting things in a group and managing the resize directly as widgets
get added / remove.

Though TBH I never know about the "special" treatment for the "Last"
pack widget - if I had that might have helped a few times!
