One of the facts that made me decide to get an android phone was the availability of KeePass, an open-source encrypted database software that allows to securely keep all critical password and numbers at hand.
Brian Pellin is the volunteer software developer who singlehandedly compiled and maintains KeePassDroid, the android version of KeePass. Being an industrial designer, and having a long experience in graphic design, I contacted Brian on July 12th 2009 to offer some assistance. He replied within 24 hours and I got back to him with an android-specific launcher icon for KeePassDroid, and a few suggestions for fine-tuning the user interface.
What do you know? Three days later Brian was already publishing an upgrade to the software, featuring the GLP’ed launcher icon and the interface tweaks. Now where else do you find software that implements user feedback so fast? Two thumbs up for Brian Pellin and Open Source!
