Adding a few items to the wishlist as requested
The ability to run the link-checker as a cronjob and also have it remove links (sites) that go 404,302 etc (variable so I can set it to only 404s or only 302s) - with the ability to do a snapshot prior to the deletes as part of the cron (just in case)
I dont think you want to check for changes to the pages as GG stated, however the ability to check for the if-modified-since to "update" dates on sites in case you only list sites for 6 months or so. (this should also be an included setting variable - time links are good and time links are new, featured, recommended etc)
Which also brings up the next feature - the ability to break a category down into featured, new , recommended etc - and have those be able to be randomly rotated from a database table per category
definitely agree with the import text file feature for HFS's
ability to select any number of sites from a search (say for a particular domain or submitter, or email) and delete all of them in one button push - no check box selects required - however the ability to also delete one-by-one if desired.
blacklist and whitelist definitely - with the ability to have a separate whitelist partner submit system - working independently of the normal submit system
ability to select more that 1 site per day by type of submitter for acceptance - say categories of submitters that can submit 5 per day etc.
theres just a few to chew on
- oh yeah - the ability to edit anything in the database myself LOL - without learning a new language
