Just thought I'd post an update, I'm now using QWassr as my first choice Twitter client (was using TwimGo prior). The interface is very clean, and the app is stable.

Some features that I really like:

1. Colour coding of tweets (blue for your tweets, red for responded tweets)
2. Shows you what service was used for the tweet (e.g. by xxx via yyy), with a URL to the service on Twitter
3. Useful Context menu options for Individual Tweets (Reply to Selected User, Reply to All, Quote Sender, Add to Favourite, Retweet, Delete, User Info)
4. The Reply to Selected User is very useful for tweets with multiple mentions (the UI gives you a popup dialog that lets you pick which user to reply to)
5. User assignable Auto Update interval (1 - 10 minutes)
6. Searches have a drop down box with historical searches you've made
7. You can stay in the search window and update

There are a few other nice features, all up this is a classy app, and I think deserves some recognition. Which reminds me, the devs blog site does not have a Donate Link. Anyone know where to send donations?

As per above, QWassr is available in Ovi Store.

Edit: Added Hyperlink
