Hello. I would like to redesign my used theme a little and change the title display layout. Now title for all pages is static like this - "My Website's name and short description".

I would like to see each page with unique title, but main page's title should be as it is now - "My Website's name and short description". I am using module News for main page. So when user enters my site, he should see a title as described on the top of this post, if he clicks on any story in News module, he should see a title "Website's name - News - Topic Title", if he enters any other module (Contact us for example), title should be - "Website's name - Contact Us". Hope you can understand me. Thank you for any ideas.
