The new update is fabulous, thank you!

One last request: could you please show the list of websites (with their favicons) in the Textarea Cache List and once the user selects a website, only this website entries will be shown. This could be done by using a tree or by diving into the website - I believe you can find the best solution.

With this mode you could easily wipe the cache of a particular website without filtering.

Also, it might be better to change the default update interval to 10 seconds.
