I am working on a small extension and now i wonder, if this concept is interesting for anybody? My extension will create a page like this:
I started with a Google-spreadsheet. In the first four columns I enter category, link, name of link and description. I have then made a script, which will create and store a thumbnail from each link, using the free service of grabzit,com. Finally I have made the extension, which will read the information from the spreadsheet, use the thumbnail and then create such a link-page.
