The font on the update bubbles looks blurry, is there some way to fix that? Unfortunately I've noticed Adobe AIR in general blurs fonts a lot.

differentiate a direct message with something to signify it's only for you.

The ability to create custom tab groups for alerts (ie. news, tech, etc. ). Some of my feeds update much slower than news feeds, so they always get bumped off the list.

If I could put fast paced updates on a separate tab, then I could check out interesting things on my slower feeds too.

In Vista, multi-user and in low-power mode, I think AlertThingy senses the loss of the network connection during power transitions. But the Oops! No internet connection box which has a Close link does not close even when the network is restored.

To create the one to rule them all, do a little searching and find what works for TweetDeck, Twhirl, Twitterific, and a whole host of other desktop social networking apps. I understand it's non-trivial to accomplish this stuff - but you have an awesome product and I'd love to see it keep growing.

Allow a user to subscribe to a twitter #hashtag like an RSS feed.

I had trouble installing on Vista Ultimate 32-bit. TweetDeck installed without issue. I had to uninstall and reinstall AlertThingy. Then it had troubles with Facebook. Facebook returned an error about invalid API.
If you want to succeed you will need to get these bugs squashed!

It just quit updating. Is it me or is it you?
BTW, I'm using it on a iMac running Leopard.

A friend tweeted, and now it shows up twice in my list. Once with his username (cwjohnston), once with his real name (Cameron Johnston). The tweets are identical, and it doesn't look like he deleted one and retweeted (I checked using search.twitter.com).

I tweeted, then got two separate, duplicate notifications about my tweet.

Will not post to twitter and have to cancel the attempted post to clear the post screen

It would be nice if more than just status updates were provided for facebook, e.g. also being able to view images people have added, and see profile updates etc.

Improve the performance as more columns are added to the app.

The scrolling is somehow inverting if I do it slowly. Works fine if its a quick scroll but jumps all over the place otherwise.

Using a Mac but I'm guessing it'll be universal if its in Air

Using the mouse scrollwheel to scroll works very inconsistently. It seems to work reliably if the mouse pointer is either 1. over the scrollbar or 2. over text that is a link (Reply, Retweet, etc.). Anywhere else, it rarely works.

The same is true of using two-finger scrolling on my Macbook Pro's touchpad.
