To me, it is awkward that the text entry is at the bottom when the tweets sort with the newest at the top. At the least, users should be able to change the position of the text entry box and the sort order of tweets.

The button to show and hide the Instafilter search box is unclear...I think the UI guidelines call for a disclosure triangle for that purpose.

For example, when I type the word open in the tweetbox, it is automatically transmitted to o followed by the pen icon.

So if you overtype your message, making the display go to tweetx2, and then you shorten it, the progress bar still shows the state from when it was tweetx2

I think the drop down to switch between "friends", "replies" and other is not the best design.

• We can see the number of new tweet in each categories
• Drop down need two click to change
• You need open drop down to see options (not cool for new user)

Personally I think a sidebar (retractable) is the best.
