In an application I developed with C#, I use a webbrowser control, it should navigate to some websites, then I would like to extract some contents from the webpages. I do it by manipulation of DOM and removing some nodes. It can be done automatically or manually with the help of user.

Then I have two modes, surfing mode and extraction mode. I think switching between modes and updating related controls and menus and responding to events... has made my program complicated (What is your advice to make it less complicated?)

Does Separation of Concerns applies to GUI components too?
