I have a big winform with 6 tabs on it, filled with controls. The first tab is the main tab, the other 5 tabs are part of the main tab. In database terms, the other 5 tabs have a reference to the main tab.

As you can imagine, my form is becoming very large and hard to maintain. So my question is, how do you deal with large UI's? How do you handle that?
