I think it would be great if there were search boxes on the admin edit pages so that if you wanted to edit a specific site, category, etc. or check a specific link, etc. you could just type in part of the name and find it.

Thanks!

The ability to edit sites is currently only available (like you said) through the admin UI- on the left side frame- the "Edit Sites" button under the header "Edit Functions" subcategory- then by choosing the Category which the site is listed under (if you can remember the Category that is - which I often can't seem to remember).

Not sure how to code the search function in php in order to point the search form function to query the MySQL table(s) containing the sites' title (or other searchable tables)?
Just not that able in PHP sorry-

I bet you could get the change implemented by Dewed if you offered to pay for it- Just kidding??

Of course there's a search box on the public side, but the results don't show which category the link is in.

I don't know enough about PHP either. I only know enough to hack other people's code.
