Airmailr is a full-featured Twitter client for the Mac OS X Dashboard. Update your status, send @replies and view DMs as well as view your timelines. Perform full Twitter searches and view user profiles.
Airmailr v 0.3 seems to work just fine on my MacBook Air (under 10.5.6). I like the way you can resize the window to see more Tweets (unique in Dashboard Twitter clients my experience). The interface is a little rough though:
- Tweets jitter as you mouse over them
- interface elements are a bit crude, for example "x" characters for close buttons
- it's slow to respond when you open the Dashboard. It seems like every other widget is updating before this one becomes responsive
- avatar images are way too small
Despite this niggles I quite like it. It's early days so hopefully it'll lose those rough edges.
