I made a little change in order to support more themes per release. Sencha Touch 2.3 now ships with 6 themes and Ext JS 4.2 has 4 and having one big list isn't going to cut it as we move forward (or even as I add more themes). So now when you try to select a framework, you will see it's a tree now.
I'm not 100% in love with a tree as you have to expand nodes to find the release you want which is clumbersome so I decided to make the tree search able. So like in a ComboBox, if you type something into the field you can search for a theme or a version.
So if you search for 'nept', it will go through and find any nodes (leaf or not) that match so it will find all the Neptune themes.
If you searched for '2.3', it will find the Sencha Touch 2.3.0 and Ext JS 2.3.0 releases and will show all the themes under it.
Would love some feedback on this to make sure it was the best route.
