Currently the Activity Window is a useful, yet simple tool for users and developers especially when working with dynamic sites and when I don't want to switch to Firefox for a single action. However, the Activity Window does not live up to its potential. Trivial enhancements could make it a far worthier tool. Most importantly, the column "Time" should be added and the URLs should be sorted according to that column by default (according to my experience that order would be useful in MOST situations). The other two columns (Address and status/filesize) ought to be clickable (currently you can click them but that doesn't do anything). Other trivial enhancements include but are not limited to: - Highlighting rows that are loading - Zebra striping Not so trivial enhancements I can come up with: - Search functionality similar to cookies. - File info - Ability to get the file directly from cache, not reloading them from source (when developing an Ajax application that reacts differently when queried via JS, this would come handy i.e.). Please note that I'm trying to preserve the simplicity, but still think it would be great if there were some more neat features below the fold.
Have you checked out the Web Inspector's Resources section? It has several of the things you mention here. That said, the activity window is a feature of Safari, the browser, not WebKit, the engine. After taking a look at the inspector, if you'd still like to see these things implemented into the activity window, please file a bug with Apple at <https://bugreport.apple.com/>. Feature requests for the web inspector can be individually filed here in Bugzilla.
