IE9 Tweaker lets you tweak the following settings in Internet Explorer 9:

• Set menu bar to be always visible
• Set menu bar on top
• Set InPrivate Filtering to be always on
• Set 3D Border. Allowing the 3D Border will add a border between the toolbar and the web window.
• Always start IE in full-screen
• Set small icons on toolbar
• Change number of maximum downloads
• Change the rows on the about:tabs page. You can set this figure between 2 -5. Internet Explorer 9 shows 2 rows of your oft-visited sites on the about:tabs page, with each row having 5 thumbnails. We have already blogged on how you can make IE9 show more rows in the about:tabs page manually.
• Create a custom Favorites Home Page to make it display your favorites.

The main feature of IE9 Tweaker is the ability to create your own customized Homepage similar to IE9  About:Tabs page.
