Every now and then, I demo my Spotifinder Ext JS app. It’s a really cool app that connects to LastFm and Spotify. I created it, to demo Ext JS concepts in my training classes. It also shows off the great theming capabilities in Ext JS.
This year, I presented advanced theming at SenchaCon and I received lots of questions about how I created the Spotifinder app theme. So I decided to write a tutorial on how to create a really cool, good looking dark theme.
