Felix by tigerbears, one of the most distinctive app.net clients to date, has updated with new features to take advantage of ADN's growing list of uniquely non-Twitter-like attributes. Namely, Felix now supports ADN's new File API, so you can store your photos and videos directly in your ADN account, and not have to worry about third-party hosting services.
Also, Felix has gotten some interface and navigation tweaks, and the usual polish, bug fixes, and performance enhancements we've come to expect from point releases.
If you're already using Felix, grab the update now. If you're not, but you want something that doesn't look or act like a Twitter app, yet still packs all the power and personality of a full on ADN client, check Felix out.
