A2003 started offering control grouping that allows you to move and
resize grouped controls together. A2007 adds additional features to
that. Don't some of those accomplish many of the things that using a
containter like a tab or subform will do? I think it's you who has

capabilities again (and to say if there's been any additional
enhancements in A2010).
