WebStart is a US$0.99 utility in the Mac App Store that lets you customize a browser home page with frequently used links, like search engines, news or weather. Yes, you can just use standard bookmarks as you are already doing, but this simple app presents your preferred links on one page.
When you open the app for the first time you'll get a brief tutorial. Basically you create topics and add relevant URLs. You can customize the fonts by color, style and size and choose the fill and background colors.
To further customize the look of your home page, drag and drop headings and topics into an order that works for you. When you are done, save it all, and the app will provide the link for your browser. You can paste it into the location where your browser sets the home page and you're ready to go. You can get a better idea how WebStart works in this YouTube video.
WebStart is handy, especially for the novice user who doesn't want to try this themselves using HTML.
