I floated this idea back in September on wp-hackers: http://comox.textdrive.com/pipermail/wp-hackers/2007-September/thread.html#14425 ([wp-hackers] adding delete/autoload to options.php)
Basically this patch allows options to be deleted from the options.php page(By checking its checkbox - a JS confirmation is done before form submitting to make sure the user intends to delete them), Viewing of Serialized data, And also groups the options by name.
Grouping is achieved by taking the first word in the term, Ie. "test" in "test_plugin_data", If there are more than 2 terms with such a groupname, then they're promoted into their own section, This makes it easier to mass-select a particular 'groups' options to delete.
An invert selection option is also available for each group, So if a user wants to delete all the RSS cache items, They can either select all the cache items to remove, or, Select the items they wish to keep(in the rss section) and click Invert.
I've attached a plugin which is identical to the patch for those not wanting to apply the patch.
The linked wp-hackers thread mentioned also having an option to set autoload, I have not yet done that (As it'll require modifying/creating other functions) yet, But would like to include it, Just not sure how in the UI it could be managed without looking too crowded.
