Add special treatment to results from github repos to show how recently he repo was updated and how many stars it has right in the results without clicking through.
I have an extension which finds links to github, then loads those pages and generates a bit of content to embed the number of stars for the repo next to the link.
When scanning results I find myself wishing I could see how many stars and how recently the repo was updated to balance these metrics as proxies for how well supported and maintained a project is.
