Best Approach to multi screen application

[jack]

New to Lazarus/Delphi

I want to build an application that acts like a windows application, flowing from screen to screen as the user works through the application.  I am a little confused about the best approach.

Should I work with one Form and swap Panels to accomplish this flow or should I build multiple forms, one for each "screen" of the application?

Thank You for sharing your experience.

I think you Should work with one Form with two partition: a TreeView on the right (navigation) and a PageControl/TabSheet on Left  to accomplish the flow (one TabSheet for each "screen" of the application)...  the repetition of this  good designer was posted today :
