Doors Won't Be The Same ! A door is an opening or closing structure used to block off an entrance, typically consisting of an interior side that faces the inside of a space and an exterior side that faces the outside of that space and the basic door technology has remained relatively the same for centuries, but an Austrian designer Klemens Torggler has designed a door that, according to his website, "opens up new applications for the door." It uses rotating squares to move the door sideways without tracks, completely eliminating the two to four square feet generally occupied by the swinging path of a conventional door. http://dayzinfos.blogspot.com/2014/03/doors-wont-be-same.html http://www.torggler.co.at/
I don't think enough developers use these currently... and are you sure your users never hit corner-case exceptions in your app? It's certainly possible to roll your own with TraceKit and Google Analytics, these services dramatically improve the reporting side for you.
