After navigating to a project and then clicking to add a new release (on path node/add/fserver-release), it would be neat if the field_fserver_project field defaulted to the current project (i.e the project one was on when clicking "add new release" and the one defined by the URL ).
A couple of times I didn't check this field and took a moment to realise why my release had been applied to a different project: namely, the alpabetically-first project on my feature server, because it was the default choice in the combobox field.
I don't really know if this is possible to change with CCK (weighting a field based on some argument / condition such as what referer or something) - it'd just be a neat usability thing to know the Release you're making is by default going to apply to the project you were viewing when you clicked 'Add new release'.
Cheers :)
