Twitter is a social network and micro-blogging service which serves me well for connecting with colleagues, friends and family. As great of a service as it is, however it does lack some minor functionality that would appease power users and new users alike.

1. Sorting function on your follower list

The current friend list does not seem to have a consistant method of listing your followers. A simple alpha sort function would be wonderful.

2. Extra data on the follower list

Also, in regards to the follower page, It would be nice to see addition data. I would like to see if someone began following me, when they did and when they last tweeted. A sort on this criteria would allow you to see which followers have abandoned their accounts and can be unfollowed.

3. Checkboxes next on the follower list for mass unfollowing

Suppose you wanted to clean out followers who haven’t tweeted in months. Checking a box and performing a mass remove of those followers.

4. Implementation of OpenID

With the increase adoption of OpenID with major organizations including AOL, Yahoo, Verisign and upcoming Firefox 3, it would make sense for Twitter to include OpenID as an alternative login feature.

5. Allow editing of tweets

My grammar is horrible. Sometimes I see a tweet from a short while ago that needs editing. I would prefer to edit the tweet instead of deleting it. Most of the time is a quick change. Possibly, disable editing after the tweet is more than 24 hours old.

6. Timeline of my account activities

I would like to see a digest of following someone, removing someone, tweets, etc. for my account. Not much of an immediate use of the information, but Twitter can have a graphical, AJAX-based interface to make it interesting.

7. Give URLs a defined character count in tweets

Often, I would like to share a URL in my tweets. Unfortunately, it is often a long URL that uses up the precious 140 character limit per tweet. Twitter shortens the URLs anyway, so why not allot 20 characters for the URL instead of the 40 of 50 that raw URL may contain. This would save me from going out to a URL shortening service, getting a short link and including it in my tweet.

8. Notification if someone unfollows you

Maki from DoshDosh suggested notifier if someone unfollowed you. I would want to know if someone decides to stop following me or if a bunch of people at once unfollow. Allow this feature to be turned on or off to for those who don’t care.

9. Grouping followers and those you follow

Many people have requested a feature which also for people associate users together. Personally, I would like a option to have a tabbed interface of groups that are relevant to me. I would have an SEO, ColdFusion, Personal Friend, and Family tags. The don’t need to be public, but that would be an nice addition.

10. View more than 20 tweets at a time

I have my preferences set to view 100 results at a time, I would to have the option to change the number of tweets I see when I look at my home page. This would be another beneficial feature to power users.

A majority of these feature requests seem like easy ways to make Twitter a more robust product that makes it easier for power-users to update and manage their tweets and followers.

What features do you think Twitter could use? Let me know in the comments.

You can also follow me on Twitter, if you would like.
