Yep, a jQuery plugin. It’s a great one, I first used it in a early version of Board. Since App Ground 1.3 jQuery Hotkeys is included there. If you have worked with adding hotkeys in a web app, you know that isn’t a fun story. Using jQuery Hotkeys it becomes a easy task, it’s developed by John Resig mostly known for developing jQuery ;-)
<picture> element haven’t seen the daylight yet, hopefully we will see it in Firefox Aurora soon. Imager.js is developed at BBC News and is a great solution for responsive images. No more loading of multiply images. In favor of other solutions Imager.js can deal with pixel density, not something always needed but sill useful sometimes. I leave the exploration to you :-)
