Question2Answer Snow theme is one of the best and stable theme for desktops. It looks nice on screens smaller than 1200px but for higher resolution QA and sidebar looks small. Modified this theme to support large desktops, here is list of changed did in this theme.
1. Large QA area and Sidebar for screens greater than 1200px. Sidebar is 300px so that you can place 300px ads in sidebar. Also changed Menu text style. Added background color to menu.
2. Changed look of vote, answer and view count.
3. Removed Vote buttons from Questions list so that it looks clean.
3. Increased height of topbar
4. Removed search bar button and increased size.
7. Fixed topbar, if user want to search or access profile options when scrolled down then it is easy.
