I used most of the programs on the link above but some of them are patched I think.I really like yaheek but I dunno if that program still works cause I was always getting kicked off mic.
I also like ytunnel
http://www.ytunnelpro.com cause of the ad blocker and iggy bin and loads of other usefull things like the auto pm reject and invite blocker aswell.And that you could save all blocked pm's and reply whenever you wanted to.
But the best client I think is yahelite and the hardest to boot it seems.And there's loads and loads of options on that client.
One last program would be cookie studio cause it grabbs your cookie from username and password and gives you your account information.But I can't find a link that would be acceptable to post here cause most of the sites hosting it are booter sites.
