follow users based on region, state, or city =)

Like in HB1 - create a list of VIPs which will never be unfollowed

Create the option for tracking the success of individual keywords - how many followers were attracted in certain amount of time

add the ability to update facebook status, browse friends updates and photos, and eventually allow us to manage our facebook business pages.

HB2 is working so well that it is possible to unfollow people before 3 days not allowing them to follow back and just creating churn. A setting to monitor and prevent HB2 from unfollowing people before that 3 days or whatever we choose is required.

This would send a DM to new followers automatically. This is NOT a feature to send automatically DMs to people from a list/group or people that are already following you, as that would be too much like spam.

Because the interface opens a new window for each account we run, it would be nice to have them hidden when we aren't actively using an account. Each window could then be accessed through the "Hummingbird II" taskbar in the top left.

let us organize friends and view them in a custom tab

HB1
Let us set a number of people we can follow or unfollow. exmp: follow 75 and then automatically stop. That way we don't over follow per hour if we get distracted.

I am really interested in finding people who follow back. A feature that allowed us to search for people by keyword AND by percentage rate of follow backs would be ideal. I would buy H2 tomorrow if you had that feature.

You first add a follower to your VIP list which would be a new feature and then you NUKE all your DMs BUT this action retains the DMs from your VIPs. Two new features would be required. My guess...around 75% of all DM is Spam and not worth a read.

a social networking broadcast tool that posts to myspace, facebook, linkedin, blogs and many more. A connection to this application would result in being able to post one post on your account and having it automatically post on all the social networks at one time.

Have a choice of one language only or exclude from a list of languages (I understand more than one so I like this option better). I usually go back to my followers list and unfollow manually the people who tweet in languages I don't understand.

The ability to use one click and retweet from one account to another and through them all at one time is going to be important in remaining active today.
