Requesting Yahoo IM feature enhacements: reconnect, multiple logins, etc

I am hoping for the following feature additions in a future version of
Yahoo Instant Messenger (http://im.yahoo.com). Anybody know where I
can submit these requests to get the most traction and/or if these
things are already being worked on?

+ Get Yahoo IM to auto-reconnect after laptop suspend/hibernate (like
AIM does)
+ Allow multiple, simultaneous login connections (from multiple
computers) like AIM does?
+ Allow a user-designated place store and retrieve chat-msg-archives
(eg, in a data partition/file-system separate from my windows/system
partition). Requires the ability to re-import existing msg-archives
into a new YahooIM software installation (eg, if I moved the data
archives from one computer to another).

Thanks for any help!
