Pressy - the Almighty Android Button! by Nimrod Back — Kickstarter In short, it's a hardware button that inserts via your headphone jack and pairs with an app, which you can then customize to leap directly to specific tasks. Nice explanatory video at the main page. It's so low-profile that I doubt it would work well with my Samsung S4 + Spigen Neo Hybrid case -- the case adds nearly 4mm of depth to the jack, and the Pressy button only extends 0.7mm beyond the case -- but a cool idea regardless. Campaign continues for several more weeks if anyone is interested.
