Syrinx, a fully customizable twitter client designed for the Mac, is seeing its first public release. Having been built for efficient workflow as well as customization, MRR Software's app sports bookmarks, searching capabilities, a pause feature, easy keyboard controls and numerous customization methods (color, sound, functionality).

Bookmarks are very useful in Syrinx. When new tweets arrive, they are colored according to the customizable bookmark color, accompanied by a sound, while the number of bookmarked tweets is badged on the dock icon. Syrinx searching capabilities allow the user to look for specific tweets, or to see if their name has come up in a certain context. What's even better is that new tweets get pulled down (so you don't miss a thing), but they won't fly away until you're ready to resume the read.

As far as controls are concerned, users can hit the spacebar to advance the bookmark one tweet at a time, use Enter / Return to reply to the currently selected tweet, while all the other popular actions are bound to the keyboard. And this is just the functionality we've discussed. Next up, Customization!

Besides letting you change your timeline background colors, your own status background and the bookmark color, Syrinx also offers several built-in themes, such as Apple, Dragobah, Hoth, Tatooine, Yavin, and, of course, a Custom theme. You can choose a system sound to notify you when new tweets have arrived, and you can tell Syrinx how often to check for updates.

Since Twitter lowers their rate limits when the servers become overwhelmed or during heavy load periods, Syrinx includes this useful option to dynamically adjust its request rate to stay under any request limit. As such, the application will automatically space out your remaining requests for the hour to make sure you don't miss a single tweet.

MRR Software's Syrinx is available for free download right here on Softpedia (Mac OS X 10.5 or later, Universal Binary). The developer is accepting donations via PayPal. Let us know if you've found this application useful.
